Given:

Distance of each lap = 372 m

Time for first lap = 186 sec

Time for second lap = 62 sec

Formula used:

Average Speed = Total Distance / Total Time

Calculation:

Total Distance = 372 m + 372 m = 744 m

Total Time = 186 sec + 62 sec = 248 sec

⇒ Average Speed = 744 m / 248 sec

⇒ Average Speed = 3 m/sec

∴ The correct answer is option (4).
