List of top Quantitative Ability and Data Interpretation Questions on Speed, Time and Distance

A flight, traveling to a destination 11,200 kms away, was supposed to take off at 6:30 AM. Due to bad weather, the departure of the flight got delayed by three hours. The pilot increased the average speed of the airplane by 100 km/hr from the initially planned average speed, to reduce the overall delay to one hour. 
Had the pilot increased the average speed by 350 km/hr from the initially planned average speed, when would have the flight reached its destination?

Excluding the halts, the speed of the bus is 50 km/ hr and including the halts it is 40 km/hr. For how many minutes does the bus stop per hour?
In a running race, when one runner allows another runner to stay ahead at the start of the race, then it is termed as startup and when runners reach the finishing line at the same time, then it is termed as dead heat. In a race of 4 km distance, Anu wins by 600m over Binu. Binu can give a startup of 200m to Caira in a 4 km race. By how much distance should Caira get startup so that the race between Anu and Caira ends in dead heat in the same race of 4 km?
A man covers half of his journey by train at 90 km/hr, one-third of the remainder by bus at 30 km/hr and the rest by cycle at 10 km/hr. The average speed during the entire journey is ______
A person reaches his office just in time when he travels at a speed of 48 kmph. When he moves at a speed of 36 kmph, he gets late by 15 minutes. Find the distance of the journey.
Two trains moving in opposite directions cross a man standing on a platform in 25 seconds and 15 seconds respectively, and they cross each other in 21 seconds. Find the ratio of the speeds of the trains.
Rohan travels 30 meters in 4 seconds, whereas Mohan travels 40 meters in 5 seconds. If both start from the same point, what distance would be travelled by Mohan by the time he is 20 meters ahead of Rohan?
The distance between A and B is \(180\) km. A starts towards B at a speed of \(30\) kmph at 9:00 a.m., and after 1 hour, B starts towards A at a speed of \(20\) kmph. At what time will they meet for the first time?
A cyclist drove one kilometer, with the wind in his back, in three minutes, and drove the same way back, against the wind, in four minutes. If we assume that the cyclist always puts constant force on the pedals, how much time would it take him to drive one kilometer without wind?
Two sea trawlers left a sea port simultaneously in two mutually perpendicular directions. Half an hour later, the shortest distance between them was 17 km and another 15 minutes later, one sea trawler was 10.5 km farther from the original than the other. Find the speed of each sea trawler.
