A boat travels 64 km in 16 hours in favor of the current and 24 km in 8 hours against the current of the river. Find the velocity of the boat in steady water and the velocity of the current with the help of graph.

Express the following statements in the form of simultaneous linear equations and solve them by drawing graphs : (iv) A boat travels 56 km in 4 hours in favour of the current and 48 km in 8 hours against the current. Find the velocity of the boat in steady water and the velocity of the current.

A boatsman can travel by his boat a distance of 30 kilometres in 6 hours in favour of the current . While he comes back in 10 hours against the current . Find the velocity of the current and the velocity of the boat in still water.

A person travels by boat 5 kilometres in 1 hour in still water. The time he requires to travel 40 kilometres against the current is 3 times the time he requires to travel the same distance in favour of the current . Find the velocity of the current .

A boat takes 6 h to travel some distance along the current on a river. It takes 10 h to travel the same distance against the current. Find out the time taken by the boat to travel that distance in the absence of any current.

A boatman can row 7 km down a river and back in 4(2)/(3) hours. If the river runs at the rate of 2 km per hour, find the rate of the pull in still water.
