Question

    A bus initially traveling at a speed of 55 km/hr

    increased its speed by 12 km/hr after ‘t’ hours and then traveled for (t + 6) hours more. If the bus covered 744 km in the last (t + 6) hours, find the distance covered in the first ‘t’ hours.
    A 220 km Correct Answer Incorrect Answer
    B 200 km Correct Answer Incorrect Answer
    C 275 km Correct Answer Incorrect Answer
    D 250 km Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ, (55 + 12) × (t + 6) = 744 Or, 67 × (t + 6) = 744 Or, t + 6 = 11 Or, t = 5 Therefore, required distance traveled = 55 × 5 = 275 km
