Question

Two trains travelling in the same direction at
40 and 22 km/h completely pass off another
in 1 minute. If the length of the first train is
125 m, what is the length of the second train​

Answer 1

Step-by-step explanation:

ANSWER

Relative speed of trains = 40 - 22 = 18 km/hr ∵ 18 km/hr = 5 m/sec

Letthe length of second train = L m Time taken to cross each other = 5L+125

∴ 5L+125=60⇒L=175 m

Answer 2

Answer:

Relative speed of trains = 40 - 22 = 18 km/hr ∵ 18 km/hr = 5 m/sec

Let

the length of second train = L m Time taken to cross each other

=

5

L+125

∴

5

L+125

=60⇒L=175 m
