    In covering a distance of 30 km, Rohit takes 2 hours more than Ronit. If Rohit doubles his speed, he would take 1 hour less than Ronit. Rohit’s speed is:

    Solutions

    Note:- Go through options to save your valuable time

    Option [b]:- speed of Rohit = 5km/h

    Then required time = 30/5 = 6 hours

    According to the question

    Required time for Ronit = ( 6 – 2 ) = 4 hours

    When Rohit doubles his speed.

    New speed of Rohit = 10km/h

    New required time = 30/10 = 3 hours

    Difference in time = ( 4 – 3 ) = 1 hour

    Now we see options [b] satisfies all the conditions of the questions so option [b] is correct.

    A boat goes 24 km upstream and 28 km downstream in 6 hours. It goes 30 km upstream and 21 km downstream in  hours. Find the speed of boat in still water.

    Solutions

    Let speed of boat in still water = x km/hr

    And speed of stream = y km/hr

    Speed of upstream = (x – y) km/hr

    Speed of downstream = (x + y) km/hr
