Question 1:

A boat covered a distance of $18 \mathrm{~km}$ upstream in 6 hours and a distance of $49 \mathrm{~km}$ down stream in 7 hours. The speed of a stream in $\mathrm{km}$.

Question 2:

Ratio between speed of boat in still water to speed of stream is $7: 3$. In downstream, boat can cover $180 \mathrm{~km}$ in 4 hours, then find the difference between speed of boat in still water and speed of stream.

Question 3:

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 ?

Question 4:

A fisherman swims to catch fishes and he on an average traveled around 36 km against the current and 60 km with the current in 8 hours. Also at the same time he can cover 45 km against the current and 90 km with the current together in 11 hours. Find the speed (in km/h)with which the current is flowing?

Question 5:

A boat running downstream covers a distance of $12 \mathrm{~km}$ in 30 minutes and while running upstream at the same speed, it covers the same distance in 36 minutes. What is the speed (in $\mathrm{km} / \mathrm{h}$ ) of the boat in still water?

Question 6:

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 7:

A man rows down a river 30 km in 6 hrs with the stream and returns in 10 hrs. The speed at which he rows in still water is:

Question 8:

Two motorboats A, and B started simultaneously travel towards each other from the point P and point Q in upstream and downstream respectively and meet each other in 28 hours. The speed of the motorboat A in still water is 166.66% of the speed of the motorboat B in still water. It is given that the difference between the speed of motorboat A in still water and the speed of the motorboat B in still water is 12 km per hour.What is the distance between point P and point Q?

Question 9:

The speed of a boat in still water is $18 \mathrm{~km/h}$ and the speed of the stream is $3 \mathrm{km/h}$. Suresh rows to a place at a distance of $105 \mathrm{~km}$ and comes back to the starting point. The total time taken by him is:

Question 10:

A motor boat has speed $30 \mathrm{~km} / \mathrm{h}$ in still water. It goes $60 \mathrm{~km}$ down stream and comes back in $\frac{9}{2}$ h. What is the speed of the stream?
