A boat can travel with a speed of 13 km/hr in still water. If the speed of the stream is 4 km/hr, find the time taken by the boat to go 68 km downstream.

The motions of Objects A, B, and C are represented on a position-time graph. Observe their lines and rank the speeds of Objects A, B, and C from slowest to fastest.

Ram and Shyarn run a race between points A and B, 5 km apart. Ram starts at 9 am from A at a speed of 5 km/ hr, reaches B, and returns to A at the same speed. Shyam starts at 9.45 am from A at a speed of 10 km/ hr, reaches B and comes back to A at the same speed. At what time do Ram and Shyam first meet each other?

Avantika can row 20 km downstream in 5 hours. If the stream flows at 2 km/hr, what is Avantika’s speed in still water?

A and B are places that are 200 kms apart. A train starts from A at the speed of 20 km/hr and another train starts from B at the same time at the speed of 30 km/hr, towards each other. At what distance from A will these two trains meet and how much time will the trains take to reach the meeting point ?

A train sets off from A at 4 P.M. at the speed of 40 km/hr. Another train sets off from A at 5:00 P.M. at the speed of 60km/hr in the same direction. At what time will the second train catch up with the first train?

Two boys A and B run a mile race. The speed of A is one mile per hour more than the speed of B. Consequently, B completes it three minutes later than A. What is the speed of A?

A Delhi bound train leaves Nagpur at 10. a.m. Another Nagpur bound train leaves Delhi at the same time. The first train completes its journey in 8 hours, while the second train requires 12 hours to reach Nagpur. When do the two trains meet?

A car crosses a man walking at 6 km/h. The man can see the things upto 450 m only in one direction due to fog. He sees the car which was going in the same direction for 4.5 minutes. What is the speed of the car?

Without stoppage, a train travel at an average speed of 150 kmph and with stoppages it covers the same distance at an average speed of 120 kmph. How many minutes per hour does the train stop?

In a 4 km race A wins by 600 m over B. B can give start of 200m to C in a 4 km race. By how much distance C gets start up so that the race between A and C ends in dead hear in the same race of 4 km?

A gives B a start of 30m or 10 seconds and end up the race of 1 km in dead heat.What is the ratio of speeds of A and B?

A can win B by 250m in a 2km race. What should be the change in distance of startup? So, that B must cover 20% less distance than that by A in the same time.

Arjun, Bhishma and Nakul run on the circular path at the speed of 20m/s, 30m/s and 50 m/s respectivley in the same direction. The circumference of the track (or path) is 600m. (i) When will they be together again for the first time? (ii) When will they be together again for the first time at the starting point?

To cover a distance of 192 km, Shatabdi Express takes 48 minutes less than an another fast express train. If their speeds differ by 20 km/hr, then their respective speeds are:

Two trains 90 m and 85 m long respectively when moving with uniform speed on parallel lines in opposite directions pass each other in 20 sec., but when moving in the same direction the faster passes the slower in 50 seconds. Their rates of travelling are: (in km/hr)

A man travels up-hill and down-hill on the road at a speed of 3 miles/hr and 4 miles/hr respectively. If he walks a distance of 60 miles in 17 hours on the road, no part of which is leveled. How much of the distance is uphill?

. The distance between two places A and B is 120 miles. A train leaves A for B and after travelling some distance with its usual speed of 24 miles per hr, meets with an accident. The accident detains the train by 1 hr and 20 min, and also causes it to reduce its speed by 4 miles/hr. If the train reaches B 2 hours later, at what distance from A must the accident have taken place?
