Solved Time Questions with Answers
1. A car travel 70 km in 30 minutes. In how much time will it cover 120 km?
Solution:
Speed = Distance/Time
= 70 km/1/2 hr
= 140 kmph
Speed = Distance/Time
140 kmph = 120 km/Time
Time = 120 km/140 kmph
= 0.85 hr
car takes 0.85 hr to cover the distance 120 km.
2. Vinay covers 180 km by car at a speed of 60 km/hr. find the time taken to cover this distance?
Solution:
Speed = 60 km/hr
Distance = 180 km
Speed = Distance/Time
60 km/hr = 180 km/Time
Time = 180 km/60 km/hr
= 3 hr
Vinay takes 3 hrs to cover the distance 180 km at a speed of 60 km/hr.
3. A train covers a distance of 45 km in 20 minutes. Find the time taken by it to cover the same distance if its speed is decreased by 12 km/hr?
Solution:
Distance covered by train = 45 km
Time taken = 20 min = 20/60 = 1/3 hr
Speed of the train = Distance covered/Time taken
= 45km/1/3 hr
= 135 km/hr
Reduced Speed = 135 km/hr – 12 km/hr
= 123 km/hr
Time = Distance Traveled/Speed
= 45/123
= 0.365hr
= 0.365*60 min
= 21.95 min
4. A man is walking at a speed of 5 km per hour. After every km, he takes a rest for 3 minutes. How much time will it take to cover a distance of 6 km?
Solution:
Rest time = Number of rests * time of each rest
= 5*3 minutes
= 15 minutes
Total Time Taken = Distance/Speed +Rest Time
= (6/5)*60+15 minutes
= 72+15
= 87 minutes
5. A car takes 3 hours to cover a distance if it travels at a speed of 45 mph. What should be its speed to cover the same distance in 2 hours?
Solution:
Distance = Speed *Time
= 45mph*3 hr= 135 miles
Speed = Distance/Time
= 135 miles/2 hrs
= 67.5 miles per hour
Therefore, car needs to travel at a speed of 67.5 miles per hour in order to travel a distance of 135 miles in a time of 2 hrs.
