Two train each of length 150m are running in opposite directions with the same speed. If they cross each other in 15 seconds, what is the speed of each train in km per hour?
- 36
- 72
- 20
- None of these
Explanation
Given:
-
Length of each train = 150 m
-
Total length to cross = 150 m + 150 m = 300 m
-
Time taken to cross = 15 seconds
-
Trains are moving in opposite directions at the same speed
Step 1: Use the formula
Time = 300 / 15 = 20 m/s
Since both trains have the same speed and are moving in opposite directions:
Step 2: Convert to km/h
