In a race, an athlete covers a distance of 354 m in 118 sec in the first lap. He covers the second lap of the same length in 59 sec. What is the average speed (in m/sec) of the athlete?

Correct option is B

Given:
Distance of first lap = 354 m
Time for first lap = 118 sec
Distance of second lap = 354 m
Time for second lap = 59 sec
Formula Used:
​$$\text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}}$$​​
Solution:
Total distance = 354 + 354 = 708 m
Total time = 118 + 59 = 177 sec
=> Average speed = $$\frac{708}{177}$$​ = 4 m/sec
