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?
Answer & Solution
Correct Answer:
Option
B
$$\eqalign{
& {\text{Average speed}} = \frac{{{\text{Total distance}}}}{{{\text{Total time}}}} \cr
& = \frac{{500 + 500}}{{625 + 375}} \cr
& = \frac{{1000}}{{1000}} \cr
& = 1{\text{ m/s}} \cr} $$
