Question

A train 60 m long passes a platform 90 m long in 10 seconds. the speed of the train is

Answer 1

Speed of train = Total distance/ Total time
= (60 m + 90 m) / 10 s
= 15 m/s

Speed of train is 15 m/s

Answer 2

Answer:

Speed of the train = 15m/s

Step-by-step explanation:

Given,

Length of the train = 60m

Length of the platform = 90m

Time taken to pass the platform = 10 seconds

To find,

The speed of the train

Recall the formula

Speed = $\frac{distance }{time}$

Solution:

Total distance traveled by train in 10 seconds = Length of the train +length of the platform

= 90 +60

= 150m

Total distance traveled by train in 10 seconds = 150m

Speed of the train = $\frac{distance }{time}$

= $\frac{150}{10}$

= 15m/s

∴Speed of the train = 15m/s
