The speed is the distance covered by an object at a particular time. The time it will take for the train to pass the jogger is 36 seconds.
<h3>What is speed?</h3>The speed is the distance covered by an object at a particular time. Therefore, it is the ratio of distance and time.
The speed of the train and the man can be written as,
- Speed of the train = 45kmph = 45×(5/18) = 12.5mps
- Speed of the man = 9kmph = 9×(5/18) = 2.5mps
Now, the time it will take for the train to completely pass the man is,
Relative speed = Distance / Time
(12.5 - 2.5) = (240 + 120)/ Time
10 = 360/Time
Time = 360/10
Time = 36 seconds
Hence, the time it will take for the train to pass the jogger is 36 seconds.
