Question

    A man starts his journey from point ‘P’ to point

    ‘Q’. He covers (1/5)th of the total distance in 2 hours and the rest in 8 hours. If he takes 10 hours to return to point ‘P’ from point ‘Q’, then determine his average speed for the complete journey if the distance between ‘P’ and ‘Q’ is 50 km.
    A 4 km/h Correct Answer Incorrect Answer
    B 8 km/h Correct Answer Incorrect Answer
    C 5 km/h Correct Answer Incorrect Answer
    D 6 km/h Correct Answer Incorrect Answer

    Solution

    ATQ,

    Average speed = total distance covered ÷ total time taken

    Total time taken = 2 + 8 + 10 = 20 hours

    Total distance covered = 50 × 2 = 100 km.

    Required average speed = 100/20 = 5 km/h
