Question

A 175 meters long train crosses a 35 meters platform in 12 seconds. What is the speed of the train in km/ hr ?

Answer 1

60km/h

First divide 175/35 and then multiply it with 12

Answer 2

The speed of train is 63 km/hr

Step-by-step explanation:

Length of train = 175 m

Length of platform = 35 m

Distance traveled by train = 175+35=210 m

Time = 12 seconds

Speed =$\frac{Distance}{Speed}=\frac{210}{12} m/s$

Speed in km /hr =$\frac{210}{12} \times \frac{3600}{1000}=63 km/hr$

Hence The speed of train is 63 km/hr
