Two trains A and B cover distances of 120 km and 180 km in 3 hours and 4 hours respectively. Which train is moving faster, A or B?

Answer:

In order to solve this problem, we need to calculate the speeds of both the trains separately. The train having greater speed moves faster. Train A: Distance travelled = 120 km Time taken = 3 hours Speed of train\[A=\frac{120}{3}=40km/h\] Train B: Distance travelled = 180 km Time taken = 4 hours Speed of train \[B=\frac{180}{4}=45km/h\] So, train B moves faster than train A.
