1. A train crossed a platform in 45 seconds travelling with a speed of 36 km/h. If the length of train is 200 meters, then what will be the length (in meters) of the platform?
- A. 250
- B. 250
- C. 250
- D. 250
Answer: Option A
Explanation:
t= 45 s
v= 36km/h = 36×(5/18)= 10m/s
S= vt = 45×10= 450m
Length of the platform= (450-200) = 250m.
