    Question

    A truck moves at a speed of 80 km/h and covers a

    distance of 160 km. If the speed is increased by 25%, how much time (in minutes) will the truck take to travel the same 160 km at the new speed?
    A 57 Correct Answer Incorrect Answer
    B 55 Correct Answer Incorrect Answer
    C 84 Correct Answer Incorrect Answer
    D 96 Correct Answer Incorrect Answer

    Solution

    ATQ;
    Original speed = 80 km/h
    Original time = 160 ÷ 80 = 2 hours
    New speed = 80 + 25% of 80 = 80 + 20 = 100 km/h
    New time = 160 ÷ 100 = 1.6 hours = 96 minutes
