    of y km/h and reaches the destination in 4 hours. If the same traveller had traveled 1 km/h faster, he would have reached the destination 1 hour earlier. If he wants to cover this distance with the speed of 2 km/h then, find the time taken to cover the distance.

    C 5.5 hours Correct Answer Incorrect Answer
    D 6 hours Correct Answer Incorrect Answer
    E none Correct Answer Incorrect Answer

    Solution

    Distance in first condition = speed × time = 4y Distance in second condition = speed × time = (y+1) × 3 = 3x+3 4y = 3y+3 y = 3 distance = 3y+3 = 12 km time taken = 12/2 = 6 hour
