In a race, an athlete covers a distance of 402 m in 134 sec in the first lap. He covers thesecond lap of the same length in 67 sec. What is the average speed (in m/sec) of theathlete?

Correct option is D

Given:

Distance covered in each lap = 402 meters

Time for the first lap = 134 seconds

Time for the second lap = 67 seconds

Formula Used:

Average Speed = $$\frac{\text{Total Distance}}{\text{Total Time}}$$​​

Solution:

Total distance covered = 402 + 402 = 804 meters

Total time taken = 134 + 67 = 201 seconds

Average Speed = $$\frac{804 }{201 }$$​= 4 m/sec

Thus, the average speed of the athlete is 4 m/sec
