Two buses start from a bus terminal with a speed of 20 km/h at interval of 10 minutes. What is the speed of a man coming from the opposite direction towards the bus terminal if he meets the buses at interval of 8 minutes?
- 1 km/hr
- 3 km/h
- 4 km/h
- 5 km/h
- 7 km/h
Explanation
Let Speed of the man is x kmph.
Distance covered in 10 minutes at 20 kmph = distance covered in 8 minutes at (20 + x) kmph.
Or, 20×1060=860×(20+x)
Or, 200 = 160 + 8x
Or, 8x = 40
Hence, x = 5kmph
