Explanation

A jogger running at 9km/h in the direction of train so relative speed will be determined by subtracting 9 from 45 km/h.

Jogger is 240 meter ahead so

Total distance = 240 + length of the train = 240 + 120 = 360

Time = Distance/Speed

To Find

Time = ?

Solution

Relative speed = 45 km/h – 9 km/h

Relative speed = 36 km/h

Now, to change it into m/sec;

Relative speed = (36 x 1000)/3600

Relative speed = 10 m/sec

Total distance = 240 + 120 = 360 m

Now,

Speed = Distance/Time

Time = Distance/Speed

Time = 360/10

Time = 30 seconds answer

Conclusion

A jogger running at 9km/h alongside a railway track is 240 meter ahead of the engine of a 120 meter long train running at 45km/h in the same direction. In 30 seconds train will pass the jogger.
