Question
A car travels from city A to city B at a speed of 60
miles per hour and returns to city A at a speed of 40 miles per hour. If the total round trip takes 5 hours, what is the distance between city A and city B? ÂSolution
ATQ, Let the distance between city A and city B be x miles. Time taken to travel from A to B = x/60 hours Time taken to travel from B to A = x/40 hours Total time = x/60 + x/40 = 5 hours Solving for x, we get x = 120 miles.
