Equal distance travel at a speed of 30 km/h , 25 km/h, and 20 km/h
Formula used:
Average speed = Total distance/Total time
Calculation:
Speed Distance Time
(Lcm of speed)
30 300 10
25 300 12
20 300 15
Total distance traveled = (300 + 300 + 300) = 900
Total time taken = (10 + 12 + 15) = 37
Average speed = 900 ÷ 37 = 24.32 km/h
∴ Average speed = 24.32 km/h
