Question

It takes a boat about 2 hours to go 16 miles downstream with the current and 4 hour to return against the current. Find the speed of the boat in still water and the speed of the current.

Answer 1

The key principles are:

a) Distance = Rate * Time

b) speed downstream = 

(Still water boat speed)+(current)

speed upstream =

(still water boat speed) - (current)

 

can you set it up now?
