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:
70 km/hr | 75 km/hr | 84 km/hr | 87.5 km/hr |
2. A man covered a certain distance at some speed. Had he moved 3 kmph faster, he would have taken 40 minutes less. If he had moved 2 kmph slower, he would have taken 40 minutes more. The distance in km is:
35 | 36$ \dfrac{2}{3} $ | 37$ \dfrac{1}{2} $ | 40 |
3. A man rides his bicycle 10 km at an average speed of 12 km/hr and again travels 12 km at an average speed of 10 km/hr. What is his average speed for the entire trip approximately?
11.2 kmph | 10 kmph | 10.2 kmph | 10.8 kmph |
4. Walking 6/7th of his usual speed, a man is 12 minutes too late. What is the usual time taken by him to cover that distance?
1 hr 42 min | 1 hr | 2 hr | 1 hr 12 min |
5. A man takes 5 hours 45 min in walking to a certain place and riding back. He would have gained 2 hours by riding both ways. The time he would take to walk both ways is
11 hrs | 8 hrs 45 min | 7 hrs 45 min | 9 hts 20 min |
6. A man walking at the rate of 5 km/hr crosses a bridge in 15 minutes. What is the length of the bridge in metres?
1250 | 1280 | 1320 | 1340 |
7. A car travelling with $ \dfrac{5}{7} $ of its actual speed covers 42 km in 1 hr 40 min 48 sec. Find the actual speed of the car.
17$ \dfrac{6}{7} $km/hr | 25 km/hr | 30 km/hr | 35 km/hr |
8. In a flight of 600 km, an aircraft was slowed down due to bad weather. Its average speed for the trip was reduced by 200 km/hr and the time of flight increased by 30 minutes. The duration of the flight is:
1 hour | 2 hours | 3 hours | 4 hours |
9. A man on tour travels first 160 km at 64 km/hr and the next 160 km at 80 km/hr. The average speed for the first 320 km of the tour is:
35.55 km/hr | 36 km/hr | 71.11 km/hr | 71 km/hr |
10. An aeroplane covers a certain distance at a speed of 240 kmph in 5 hours. To cover the same distance in 1$ \dfrac{2}{3} $ hours, it must travel at a speed of:
300 kmph | 360 kmph | 600 kmph | 720 kmph |
