Time and Distance Questions and Answers
Question : 1 The ratio between the speeds of two trains is 7 : 8. If the second train runs 400 km in 4 hours, then the speed of the first train is:
A. 70 km/hr
B. 75 km/hr
C. 84 km/hr
D. 87.5 km/hr
[expand title=”Show Answer” swaptitle=”Hide”]
Correct Answer : D
Explanation :
Let the speed of two trains be 7x and 8x km/hr.
Then, 8x = 400/4 = 100
x = 100/8 = 12.5
Speed of first train = (7 x 12.5) km/hr = 87.5 km/hr.

Question : 2 Excluding stoppages, the speed of a bus is 54 kmph and including stoppages, it is 45 kmph. For how many minutes does the bus stop per hour?
A. 9
B. 10
C. 12
D. 20
[expand title=”Show Answer” swaptitle=”Hide”]
Correct Answer : B
Explanation :
Due to stoppages, it covers 9 km less.
Time taken to cover 9 km = (9/54) x 60 min = 10 min.

Question : 3 If a person walks at 14 km/hr instead of 10 km/hr, he would have walked 20 km more. The actual distance travelled by him is:
A. 50 km
B. 56 km
C. 70 km
D. 80 km
[expand title=”Show Answer” swaptitle=”Hide”]
Correct Answer : A
Explanation :
Let the actual distance travelled be x km.
Then, x/10 = (x + 20)/14
14x = 10x + 200
4x = 200
x = 50 km.

Question : 4 An airplane covers a certain distance at a speed of 240 kmph in 5/3 hours. To cover the same distance in 1 hours, it must travel at a speed of:
A. 300 kmph
B. 360 kmph
C. 600 kmph
D. 720 kmph
[expand title=”Show Answer” swaptitle=”Hide”]
Correct Answer : D
Explanation :
Distance = (240 x 5) = 1200 km.
Speed = Distance/Time
Speed = 1200/(5/3) km/hr.
Required speed = 1200 x (5/3) km/hr = 720 km/hr.

Question : 5 A person crosses a 600 m long street in 5 minutes. What is his speed in km per hour?
A. 3.6
B. 7.2
C. 8.4
D. 10
[expand title=”Show Answer” swaptitle=”Hide”]
Correct Answer : B
Explanation :
Speed = 600/(5 x 60) m/sec.
= 2 m/sec.
Converting m/sec to km/hr (see important formulas section)
= 2 x (18/5)km/hr
= 7.2 km/hr.
