  1. Excluding stoppages, the speed of a bus is 54 km/hr. and including stoppages it is 45 km/hr. for how many minutes does the bus stop per hour ?

    Due to stoppages, it covers 9 km. less per hour.
    Required ans is, time taken to cover 9 km.

    Correct Option: B

    Due to stoppages, it covers 9 km. less per hour

    Required time = Time taken to cover 9 km.
    = 9 / ( 54 /60) min
    = 10 min

  1. A train cover a distance in 50 minutes, if it runs at a speed of 48 km per hour on an average. The speed at which the train must run to reduce the time of journey to 40 minutes ?

    Total Distance = 48 x (50/60) km.
    = 40 km

    Required speed = [40 / (40/60)] km.

    Correct Option: C

    Total Distance = 48 x (50/60) km.
    = 40 km

    Required speed = [40 / (40/60)] km.
    = (40 x 60 )/ 40 km/hr.
    = 60 km/hr.

  1. Laxman has to cover a distance of 6 km in 45 minutes . If he cover one half of the distance in 2/3rd time . what should be his speed to cover the remaining distance in the remaining time?

    ∵ Time left = (1/3 X 45/60) hr.
    = 1/4 hr.
    Distance left = 3km

    ∴ speed required = [3 / (1/4) ] km/hr.

    Correct Option: C

    ∵ Time left = (1/3 X 45/60) hr.
    = 1/4 hr.
    Distance left = 3km

    ∴ speed required = [3 / (1/4) ] km/hr.
    = 3 x 4
    =12km/hr .

  1. A plane flies along the four sides of a square field at a speed of 200, 400, 600 and 800 km/hr. Then find the average speed of plane around the square field.








  1. View Hint View Answer Discuss in Forum

    Let the side of the square field be x and the speed of plane be y

    x/200 + x/400 + x/600 + x/800 = 4x/y

    Correct Option: D

    Let the side of the square field be x and the average speed of plane be y

    x/200 + x/400 + x/600 + x/800 = 4x/y
    ⇒ 25x/2400 = 4x/y
    ⇒ y =384

    ∴ Average speed is 384 km/hr

  1. In how many minutes will Rohit cover a distance of 800 m, if he runs at speed of 10 km/hr?








  1. View Hint View Answer Discuss in Forum

    Speed in m/sec = Speed in km/hr x 5/18

    Correct Option: D

    Rohit's speed = 10 Km/hr = (10 x 5/18) m/sec = 50/18 m/sec

    Time taken to cover 800 m = (800 / (50/18) ) sec
    = (800 x 18/50) sec = 288 sec = 4 min 48 sec
