In a race, there are 4 members in a team. Each member has to cover 5 km one after another. If the total time taken is 30 minutes, then what would have been the average speed?
Answer & explanation
Correct answer: option 2
Total distance = 5 + 5 + 5 + 5 + 5 = 20 km
Total time taken = 30 minutes = 0.5 hour
Average speed = \(\frac{20}{0.5}\) = 40 km/hr
