Speed Time and Distance Test Paper 1
1) A running man crosses a bridge of length 500 meters in 4 minutes. At what speed he is running?
- 8.5 km/hr
- 7.5 km/hr
- 9.5 km/hr
- 6.5 km/hr
The correct answer is (B)
Answer with explanation:
- 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
2) 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?
- 300 km/hr
- 280 km/hr
- 250 km/hr
- 240 km/hr
The correct answer is (B)
Answer with explanation:
Distance to be covered = Speed x Time
= 140 * 2 = 280 km
Time = 1 hour
Required Speed =280⁄1= 280 km/hr (Option B)
3) A jogger is running at a speed of 15 km/hr. In what time he will cross a track of length 400 meters?
- 96 sec
- 100 sec
- 104 sec
- 110 sec
The correct answer is (A)
Answer with explanation:
4) A horse covers a distance of 1500 meters in 1 minute 20 seconds. At what speed the horse is running?
- 67.2 km/hr
- 67.7 km/hr
- 67. 5 km/hr
- 67.9 km/hr
The correct answer is (C)
Answer with explanation:
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
5) A cyclist moving at a speed of 20 km/hr crosses a bridge in 2 minutes. What is the length of the bridge?
- 555.5 m
- 444.4 m
- 777.7 m
- 666.6 m
The correct answer is (D)
Answer with explanation:
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
