    Question

    A bike travels the same distance in 'h + 2.5' hours

    compared to a truck's 'h' hours from point 'P' to point 'Q'. Should the trip be completed in half by truck and half by bike, the total travel time would be 6.25 hours. Calculate how long it takes the truck to go 600 km at '12h' km/h.
    A 5 hrs Correct Answer Incorrect Answer
    B 15 hrs Correct Answer Incorrect Answer
    C 12 hrs Correct Answer Incorrect Answer
    D 10 hrs Correct Answer Incorrect Answer
    E none of these Correct Answer Incorrect Answer

    Solution

    ATQ, Difference between the time take by the truck and the bike to cover the same distance = h + 2.5 - h = 2.5hours So, the truck alone would take 6.25 - (2.5/2) = 5 hours to cover the distance alone So, h = 5 So, required time = 600 ÷ (12 × 5) = 10 hours
