Downstream 81577
The water in the river has a speed of 4.8 km/h relative to the bank. A boat in still water has a speed of 12.6 km/h.
a) What is the boat's speed relative to the shore if it is sailing downstream and upstream of the river?
b) What path will the boat travel if it first moves 2.5 h upstream and then 1.5 h downstream?
