Question

# The train covers 20 km in 15 minutes. How much distance will the car cover in 15 minutes if the speed of car is 60% of the speed of the train?

A

3hrs 45min

B

4hrs45min

C

5hrs45min

D

2hrs45min

Solution

## The correct option is A 3hrs 45min Given that speed of car = 60% of speed of train Now, we know that the speed is directly proportional to the distance since the time taken remains constant. Let x be the distance covered by car. The distance travelled and the amount of petrol consumed are directly proportional AB= Constant A1B1 = A2B2 Now, we can say, Speed of carSpeed of train = Distance covered by carDistance covered by train 60100 = x20 ⇒ x = 12 km
