A boat sailing through a river moved eastward for 5 km, then cross the river by moving 3 km southward. On reaching the other side it moved westward through 1 km and reached the dock. Find the distance covered by the boat in km.

boat which has a speed of 5 km/hr in still water crosses a river of width 1 km along the shortest possible path in 15 minutes. Then what is the velocity of the river water in km/hr ?

A man can swim at the rate of 5kmh−1 in still water. A 1−km wide river flows at the rate of 3 km h−1. The man wishes to swim across the river directly opposite to the starting point. How much time will he take to cross the river

1) The speed of a boat in still water is 5km/hr. If the speed of the boat against the stream is 3 km/hr, what is the speed of the stream?1.5 km/hr2 km/hr2.5 km/hr1 km/hr

A boat travels downstream from A to B, halts for 5 minutes at B, then travels upstream to C. The entire trip takes 4 hrs. Had the boat travelled the entire distance in still water, the boat would have taken 4 hrs. If the speed of the boat in still water and the speed of the stream are 10 km/hr and 2 km/hr respectively, find BC (in km).

A man (M) is standing on the bank of a river that is 0.8 miles0.8 miles wide. He wants to reach a house (B) on the opposite shore that is 1.4 miles1.4 miles downstream. The man can row the boat 3mph3⁢mph and can walk 4.5mph4.5⁢mph. Find the distance between the house and the point (P) where he should dock his boat in order to minimize the total time he would need to reach the house. Enter the exact answer or round to the nearest hundredth.
