Question: 1 -

A cyclist moving at a speed of 20 km/hr crosses a bridge in 2 minutes. What is the length of the bridge?

Options:

  1. 555.5 m

  2. 666.6 m

  3. 444.4 m

  4. 777.7 m

    5. Answer:

    666.6 m
    Solution:

    The length of the bridge is equal to the distance covered by the cyclist at a speed of 20 km/hr in 2 minutes.

    So, Distance = Speed * Time

    Speed = 20 km/hr

    Speed in m/s = 20 *5⁄18=100⁄18→50⁄9 m/s

    Time= 2 minutes →2 * 60 = 120 seconds

    Required distance =50⁄9* 120=6000⁄9= 666.6 meters

Question: 2 -

A horse covers a distance of 1500 meters in 1 minute 20 seconds. At what speed the horse is running?

Options:

  1. 67. 5 km/hr

  2. 67.7 km/hr

  3. 67.2 km/hr

  4. 67.9 km/hr

    5. Answer:

    67. 5 km/hr
    Solution:

    Distance = 1500 meters

    Time = 1 minute 20 seconds ⟶60+20=80 seconds

    So, Required Speed =1500⁄80=75⁄4m/s

    We need answer in km/hr:

    So, Speed in km/hr =75⁄4*18⁄5= 67.5 km/hr

Question: 3 -

A running man crosses a bridge of length 500 meters in 4 minutes. At what speed he is running?

Options:

  1. 7.5 km/hr

  2. 9.5 km/hr

  3. 8.5 km/hr

  4. 6.5 km/hr

    5. Answer:

    7.5 km/hr
    Solution:

    Apti Speed time and distance10

    • Distance = 500 meters
    • Time = 4 minutes ⟶ 4 x 60 = 240 seconds

    Speed =500⁄240=25⁄12m/s

    We need answer in km/hr:

    Speed in km/hr=25⁄12*18⁄5=90⁄12⟶30⁄4= 7.5 km/hr

Question: 4 -

A jogger is running at a speed of 15 km/hr. In what time he will cross a track of length 400 meters?

Options:

  1. 104 sec

  2. 110 sec

  3. 96 sec

  4. 100 sec

    5. Answer:

    96 sec
    Solution:

    Apti Speed time and distance12

Question: 5 -

A car running at a speed of 140 km/hr reached its destination in 2 hours. If the car wants to reach at its destination in 1 hour, at what speed it needs to travel?

Options:

  1. 250 km/hr

  2. 240 km/hr

  3. 300 km/hr

  4. 280 km/hr

    5. Answer:

    280 km/hr
    Solution:

    Distance to be covered = Speed x Time

    = 140 * 2 = 280 km

    Time = 1 hour

    Required Speed =280⁄1= 280 km/hr
