# What is the Length of Train in Meters?

The length of the train and that of a platform are equal. If with the speed of 90 km/hr. the train crosses the platform in 1 minute, the length of the train in meters is

- 575
- 650
- 750
- 800

**Answer: (c) 750m
Explanation:-**

Given – The length of the train = length of platform = X m

and speed of train = 90km/hr

taken time by train across the platform = 1min

Speed into m/sec = 90 x 5/18 = 25m/sec

and time in sec = 1 x 60 = 60 sec.

Distance = speed x time

According to question,

2X = 25 x 60 = 1500

X = 1500/2 = 750m

Hence, the length of the train is 750m
