In a race, a cyclist covers a distance of 500 m in 625 sec in the first lap. He covers the second lap of the same length in 375 sec. What is the average speed (in m/sec) of the cyclist?

Solution (By Examveda Team)

$$\eqalign{ & {\text{Average speed}} = \frac{{{\text{Total distance}}}}{{{\text{Total time}}}} \cr & = \frac{{500 + 500}}{{625 + 375}} \cr & = \frac{{1000}}{{1000}} \cr & = 1{\text{ m/s}} \cr} $$
