The speed of the boat in still water is 13.2 km / h, and the speed of the river is 3 km / h. Find the speed of the boat upstream and upstream of the river.
Downstream speed = boat speed + current speed = 13.2 + 3 = 16.2 km / h.
Upstream speed = boat speed – current speed = 13.2 – 3 = 10.2 km / h.
Answer: 1. a = 23.8 mm. 2. Flow rate. 16.2 km / h, against the flow 10.2 km / h
