In a race, an athlete covers a distance of 360 m in 60 sec in the first lap. He covers thesecond lap of the same length in 180 sec. What is the average speed (in m/sec) of theathlete?

Correct option is C

Given:

Distance of each lap = 360 m

Time taken for the first lap = 60 sec

Time taken for the second lap = 180 sec

Formula Used:

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

Solution:

Total Distance = 360m + 360m = 720m

Total Time = 60sec + 180sec = 240sec

Average Speed = $$\frac{720 }{240} = 3 \, \text{m/sec}$$​​
