Basics of Core Java

This Test will cover basic concepts of Time, Speed, and Distance section of Numerical Reasoning Topic.
Q. The ratio between the speeds of two trains is 7:8. If the second train runs 400 kms in 4 hours, then the speed of the first train is?
Q. A man in a train notices that he can count 21 telephone posts in one minute. If they are known to be 50 meters apart, then at what speed is the train travelling?
Q. A certain distance is covered by a cyclist at a certain speed. If a jogger covers half the distance in double the time, the ratio of the speed of the jogger to that of the cyclist is?

Q. The speed of the car increases by 2km/hr after every one hour. If the distance travelled in the first one hour was 35 kms, what was the total distance travelled in 12 hours?
Q. Aditya left for city A from city B at 5:20 am. He travelled at the speed of 80 km/hr for 2 hours 15 minutes. After that the speed was reduced to 60 km/hr. If the distance between two cities is 350 kms, at what time did Aditya reach city A?
Q. A person has to cover a distance of 6 km in 45 minutes. If he covers one-half of the distance in two-third of the total time, then to cover the remaining distance in the remaining time, his speed (in km/hr) must be?
Q. A person travels from P to Q at a speed of 40 kmph and returns by increasing his speed by 50%. What is his average speed for both the trips?
Q. A car driver travels from the plains to a hill station, which are 200 km apart at an average speed of 40 km/hr. In the return trip, he covers the same distance at an average speed of 20 km/hr. The average speed of the car over the entire distance of 400 km is?

Q. The average speed of a train in the onward journey is 25% more than that in the return journey. The train halts for one hour on reaching the destination. The total time taken for the complete to and fro journey is 17 hours, covering a distance of 800 km. The speed of the train in the onward journey is?
Q. A, B and C are on a trip by a car. A drives during the first hour at an average speed of 50 km/hr. B drives during the next 2 hours at an average speed of 48 kmph. C drives for the next 3 hours at an average speed of 52 kmph. They reach their destination after exactly 6 hours. Their mean speed was?
Q. A car travels the first one-third of a certain distance with a speed of 10 km/hr, the next one-third distance with a speed of 20km/hr, and the last one-third distance with a speed of 60 km/hr. The average speed of the car for the whole journey is?
Q. Starting from his house one day, student walks at a speed of 2.5 kmph and reaches his school 6 minutes late. Next day he increases his speed by 1 kmph and reaches the school 6 minutes early. How far is the school from his house?

Q. 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?
Q. A car travels from P to Q at a constant speed. If its speed was increased by 10 kmph, it would have taken one hour lesser to cover the distance. It would have taken further 45 minutes lesser if the speed was further increased by 10 kmph. What is the distance between the P and Q?
Q. A covers a distance of 715 km at a constant speed. If the speed of the car would have been 10 kmph more, then it would have taken 2 hours less to cover the same distance. What is the original speed of the car?
