Question

A 60 metre long train is running at a speed of 40 km per hour it will cross a railway platform 90 metre long in

Answer 1

Explanation:

Given A 60 metre long train is running at a speed of 40 km per hour it will cross a railway platform 90 metre long in

• Length of the train = 60 m
• Length of the platform = 90 m
• Now train running at a speed of 40 km/hr has to cover a distance of 60 + 90 + 60
•                                                                                                             = 210 m is the time the driver touches the platform.
• Now 40 km / hr = 40 x 1000 / 60
•                             = 666.66 m / min
• So the time taken to pass the platform will be = 210 / 666.66
•                                                                           = 0.31 min
•                                                                             = 18.6 sec
• Given A 60 metre long train is running at a speed of 40 km per hour it will cross a railway platform 90 metre long in
• Length of the train = 60 m
• Length of the platform = 90 m
• Now train running at a speed of 40 km/hr has to cover a distance of 60 + 90 + 60
•                                                                                                             = 210 m is the time the driver touches the platform.
• Now 40 km / hr = 40 x 1000 / 60
•                             = 666.66 m / min
• So the time taken to pass the platform will be = 210 / 666.66
•                                                                           = 0.31 min
•                                                                             = 18.6 sec
