A boat travels from south bank to north bank of a river with a maximum speed of `8km//h`. To arrive at a point opposite to the point of starts, the boat should starts at an angle:

A boat travels from south bank to north bank of a river with a maximum speed of 8km//h . A river current flows from west to east with a speed of 4 km/h. To arrive at a point opposite to the point of start, the boat should start at an angle:

A boat travels upstream at the speed of 20 km/h and downstream at the speed of 30 km/h. What is the speed of the boat.

A river 400 m wide is flowing at a rate of 2.0 m//s .A boat is sailing at a velovity of 10 m/s with respect to the water in a direaction perpendicular to the river . How far from the point directly opposite to the starting point does the boat reach the opposite bank

A river is 20 m wide. River speed is 3 m//s. A boat starts with velocity 2sqrt2 m//s at angle 45^@ from the river current (relative to river) (a) Find the time taken by the boat to reach the opposite bank. (b) How far from the point directly opposite to the starting point does the boat reach the opposite bank?
