1. The ratio of the speeds of a train and a man is 6:1. The length of the train is 650 m and crosses a pole in 1 minute 5 seconds. In how much time will the man cross the 240m long platform?
- A. 1min 24sec
- B. 1min 24sec
- C. 1min 24sec
- D. 1min 24sec
Answer: Option D
Explanation:
V of train=650/65=10 m/s
So, v of man=10/6=5/3 m/s
So, time=240/(5/3)=144s=2 min 24 sec
