Question
A taxi moving at a speed of 72 km/h covers a distance of
108 km. If the speed is increased by 50%, how much time (in minutes) will the taxi take to travel the same 108 km at the new speed?Solution
ATQ;
Original speed = 72 km/h
Original time = 108 ÷ 72 = 1.5 hours
New speed = 72 + 50% of 72 = 72 + 36 = 108 km/h
New time = 108 ÷ 108 = 1 hour = 60 minutes
