Question

two trains moving in the same direction at 60 km /hr and 40 km / hr. the faster train crosses a man in the slower train in 18 s. find the length of the faster train​

Answer 1

Answer:

100 m

Step-by-step explanation:

Two trains moving in the same direction at 60 km /hr and 40 km / hr. the faster train crosses a man in the slower train in 18 s. find the length of the faster train​

Both Train moving in Same Direction

Distance = Speed * Time

Distance covered by Faster Train in 18 sec =  60 * (18/3600) = 3/10  km

3/10 km = 1000 * 3/10 = 300 m

Distance covered by man in Slower Train in 18 sec =  40 * (18/3600) = 1/5  km

1/5 km = 1000 * 1/5 = 200 m

Length of Faster Train = 300 - 200 = 100 m
