    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?
    A 57 Correct Answer Incorrect Answer
    B 55 Correct Answer Incorrect Answer
    C 60 Correct Answer Incorrect Answer
    D 96 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    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
