Question

A person sets to cover a distance of 12km in 45min .If he covers 3/4 of the distance in 2/3rd time .What should be his speed to cover the remaining distance in the remaining time

Answer 1

D = 12 km

T = 45 min

3/4D = (3/4)*12 = 9 km

Remaining distance = 12-9 = 3 km

2/3T = (2/3)*45 = 30 min

Remaining time = 45 - 30 = 15 min = 1/4 Hr

Speed for remaining distance =  3/(1/4) = 12 km/Hr

12 km /Hr
