Question 1

A boat goes 2 km upstream and 3 km downstream in 20 minutes. It goes 7 km upstream and 2 km downstream in 53 minutes. What is speed (in km/h) of the boat in still water?

Question 2

A boat goes 15 km upstream and 22 km downstream in 5 hours. It goes 20 km upstream and km downstream in hours. What is the speed (in km/hr) of stream?

Question 3

A boat can go 30 km downstream and 24 km upstream in 2 hours 27 minutes. Also, it can go 10 km downstream and 4 km upstream in 37 minutes. What is the speed of the boat upstream (in km/h)?

Question 4

A boat can cover 36 km downstream and 16 km upstream in 10 hours. It can cover 3 km downstream and 1.2 km upstream in 48 minutes. What is the speed (in km/hr) of the boat when going upstream?

Question 5

A boat can cover a distance of 7.2km downstream and 3.2 km upstream in 2 hours. It can also cover 1.5 km downstream and 0.6 km upstream in 24 minutes. What is the speed of the boat when going downstream in km/h)?

Question 6

A boat can row 42 km upstream in 7 hours and the same distance downstream in 6 hours. What is the speed (in km/hr) of the boat in still water?

Question 7

A man can row a distance of 900 metres against the stream in 12 minutes and returns to the starting point in 9 minutes. What is the speed (in km/h) of the man in still water?

Question 8

A boat can go 5 km upstream and  km downstream in 45 minutes. It can also go 5 km downstream and 2.5 km upstream in 25 minutes. How much time (in minutes) will it take to go 6 km upstream?

Question 9

Speed of a boat in still water is 12 kmph and that of the current is 3 kmph. A man rows a boat upstream up to 135 km and returns downstream to the starting point. Find the total time taken for the entire journey in hours.

Question 10

The speed of a boat in still water is 13 km/hr and the speed of stream is 6 km/hr. If takes 6 hours more to sail in upstream than in the downstream. Find the distance travelled.
