Question
A man must travel 600 km in 12 hours. If he traveled the
first 40% of the journey at a constant speed of 80 km/h, at what speed must he travel the remaining distance so that he finishes the journey on time?Solution
ATQ, 40% of 600 = 240 km Time taken to travel 240 km = 240 ÷ 80 = 3 hours Remaining distance = 600 - 240 = 360 km Remaining time = 12 - 3 = 9 hours So, speed at which remaining distance is to be traveled = 360 ÷ 9 = 40 km/h
