To find the distance traveled by the train, we need to use the formula relating speed, distance, and time. The key is to ensure that all units are consistent before performing calculations. Here, the speed is given in kilometers per hour (km/h), and the time is given in minutes. We must convert the time into hours to match the speed's unit.
Since there are 60 minutes in an hour, we convert 20 minutes to hours:
\[ T = 20 \text{ minutes} \times \frac{1 \text{ hour}}{60 \text{ minutes}} = \frac{20}{60} \text{ hours} = \frac{1}{3} \text{ hours} \]The formula for distance is:
\[ \text{Distance} = \text{Speed} \times \text{Time} \]\[ D = S \times T \]The train will travel 25 km in 20 minutes.
A) 25 km is the correct distance traveled by the train.
To find the area of the square, we first need to determine the length of one side of the square. The total number of poles and the distance between consecutive poles will help us calculate the perimeter, and subsequently, the side length.
Understand the pole arrangement: When poles are fixed to fence a square, the number of poles is equal to the number of segments formed by the poles along the perimeter. For a closed shape like a square, if there are \(N\) poles, there are also \(N\) segments between them along the perimeter.
Calculate the perimeter: Given the total number of poles is 48. Given the distance between 2 poles is 5 m. Since there are 48 poles, there are 48 segments of 5 m each along the perimeter of the square.
Total perimeter \(P = \text{Number of poles} \times \text{Distance between two poles}\)
\[ P = 48 \times 5 \text{ m} \] \[ P = 240 \text{ m} \]Calculate the side length of the square: A square has 4 equal sides. Let the side length be \(s\). The perimeter of a square is given by \(P = 4s\).
\[ 240 \text{ m} = 4s \] \[ s = \frac{240}{4} \text{ m} \] \[ s = 60 \text{ m} \]Calculate the area of the square: The area of a square is given by \(A = s^2\).
\[ A = (60 \text{ m})^2 \] \[ A = 3600 \text{ m}^2 \]B) 3600 m² is the correct area of the square.
This problem involves compound interest. We are given the principal amount, the final amount, and the time period. We need to find the annual rate of compound interest. The formula for compound interest will be used to solve this problem.
The formula for the final amount (\(A\)) when interest is compounded annually is:
\[ A = P \left(1 + \frac{r}{100}\right)^n \]Divide both sides by 1000:
\[ \frac{1440}{1000} = \left(1 + \frac{r}{100}\right)^2 \]\[ 1.44 = \left(1 + \frac{r}{100}\right)^2 \]Subtract 1 from both sides:
\[ 1.2 - 1 = \frac{r}{100} \]\[ 0.2 = \frac{r}{100} \]Correct Option: B) 20% is the calculated rate of compound interest.
The following pie chart shows the total ocean cover by four oceans, Arctic, Indian, Atlantic and Pacific. 1st sector: Arctic = 4%, 2nd sector: Indian = 22%, 3rd sector Atlantic = 25% and 4th sector Pacific = 49%. Based on the pie chart, answer the given question.
If the four oceans cover an area of almost 130 million square miles in total, then what area is covered by the Pacific Ocean?
74 million square miles
65 million square miles
63.7 million square miles
64 million square miles
The problem requires calculating the area covered by the Pacific Ocean using the given pie chart percentages and the total ocean area.
Calculate the Pacific Ocean area:
\[ \text{Pacific Ocean Area} = \frac{49}{100} \times 130 = 63.7 \text{ million square miles} \]Thus, the area covered by the Pacific Ocean is 63.7 million square miles.
Correct Option: C) 63.7 million square miles

To find the average speed, we need to calculate the total distance traveled and the total time taken. Since the aeroplane flies along the sides of an equilateral triangle, each side has the same length. We will assume a convenient length for each side to simplify calculations and then use the formula for average speed: Average Speed = Total Distance / Total Time.
Let the length of each side of the equilateral triangle be \(d\) km. Since there are three sides, the total distance traveled by the aeroplane is \(3d\) km.
The speeds along the three sides are given as \(v_1 = 300 \text{ km/h}\), \(v_2 = 200 \text{ km/h}\), and \(v_3 = 240 \text{ km/h}\).
Calculate the time taken to travel each side:
Time for the first side (\(t_1\)):
\[ t_1 = \frac{\text{Distance}}{\text{Speed}_1} = \frac{d}{300} \text{ hours} \]Time for the second side (\(t_2\)):
\[ t_2 = \frac{\text{Distance}}{\text{Speed}_2} = \frac{d}{200} \text{ hours} \]Time for the third side (\(t_3\)):
\[ t_3 = \frac{\text{Distance}}{\text{Speed}_3} = \frac{d}{240} \text{ hours} \]Calculate the total time taken (\(T\)):
\[ T = t_1 + t_2 + t_3 = \frac{d}{300} + \frac{d}{200} + \frac{d}{240} \]Find a common denominator for the fractions. The least common multiple (LCM) of 300, 200, and 240 is 1200.
\[ T = d \left( \frac{1200/300}{1200} + \frac{1200/200}{1200} + \frac{1200/240}{1200} \right) \]\[ T = d \left( \frac{4}{1200} + \frac{6}{1200} + \frac{5}{1200} \right) \]\[ T = d \left( \frac{4+6+5}{1200} \right) = d \left( \frac{15}{1200} \right) \]\[ T = \frac{15d}{1200} = \frac{d}{80} \text{ hours} \]Calculate the average speed:
\[ \text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}} = \frac{3d}{T} \]\[ \text{Average Speed} = \frac{3d}{d/80} \]\[ \text{Average Speed} = 3d \times \frac{80}{d} \]\[ \text{Average Speed} = 3 \times 80 = 240 \text{ km/h} \]Correct Option: B) 240 km/h
