The boat’s own speed is 8 km / h. the speed of the current is 3 km / h. find the speed of the boat along the river, the speed of the boat against the current, the distance traveled by the boat along the river in 3 hours, the distance traveled by the boat against the river in 4 hours.
downstream speed:
8km / h + 3km / h = 11km / h
upstream speed:
8km / h-3km / h = 5km / h
distance downstream in 3 hours:
3h * 11km / h = 33km
distance upstream in 4 hours:
4h * 5km / h = 20km
