Buses start from a bus terminal with a speed of 20 km/hr at intervals 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 intervals of 8 minutes ?
A. 3 km/hr
B. 4 km/hr
C. 5 km/hr
D. 7 km/hr
Answer: Option C
Solution(By Examveda Team)
Let the speed of the man be x km/hrThen, Distance covered by the bus in 2 minutes = Distance covered by the man in 8 min
$$\eqalign{ & \Rightarrow 20 \times \frac{2}{{60}} = x \times \frac{8}{{60}} \cr & \Rightarrow x = \left( {\frac{2}{3} \times \frac{{60}}{8}} \right) \cr & \Rightarrow x = 5{\text{ km/hr}} \cr} $$
