Question 1:

A boat goes 24 km upstream in 6 hours and travels the same distance downstream in 144 minutes. What is the speed of the current?

Question 2:

A man can row $900 \mathrm{~m}$ against the stream in 12 minute and returns to the same point in 9 minute. What is the speed of stream in km/hr?

Question 3:

A boat goes 70km downstream in 14 hours and a distance of 48km upstream in 12 hours. Find the speed of the stream. (In kmph )

Question 4:

A boatman can cross a river of $120 \mathrm{~km}$ length and came back to its initial point in $9 \mathrm{hrs}$. If speed of boat is thrice than that of the speed of stream then find the speed (in km/hr) of stream?

Question 5:

Ratio of speed of a boat in upstream  to its speed in downstream is $3: 7$. If speed of boat in still water is $35 \mathrm{~km} / \mathrm{hr}$, then, find the distance covered by the boat in upstream in 8 hours ? (in km)

Question 6:

In still water, Rajni can row $135 \mathrm{~km}$ in $7.5$ hours, while she can row $48 \mathrm{~km}$ upstream in 4 hours. What is the speed of the current in km/hr?

Question 7:

A boat covers 60 km downstream in 5 hours. If the difference between the downstream and upstream speed of the boat is 4 km/hr, then find the speed of the boat in still water?

Question 8:

A motorboat covers a distance of 48 km upstream in one hour more than the time taken to cover the same distance downstream. If the speed of the current of the river is 4 km/h, then what is the speed (in km/h) of the boat in still water?

Question 9:

A boat takes 14 minutes to travel $8.4 \mathrm{~km}$ upstream. If the ratio of the speed of the boat to that of the stream is $6: 1$, then how much time (in minutes) will the boat take to travel $33.6 \mathrm{~km}$ downstream?

Question 10:

A boat can go 10 km upstream and 11 km downstream in a total time of 52 minutes. If the speed of the stream is 5 km/h, then what is the speed (in km/h ) of the boat when going downstream ?
