Question

P covers the first one hour of his travel at 50km/hr and the next two hours at 70km/hr.What is the average speed

Answer 1

47.5kmph

Explanation:

average speed = total distance ÷ total time

distance a = 1×50= 50 km

distance b = 2×70= 140km

total time = 1+3 = 4 hrs

avg. speed = 190 ÷ 4= 47.5 km/h.
