Question

Pleaseeeeee help
It takes Carla's boat 1/2 hour to go 8 miles downstream and 1 hour to make the return trip upstream. Find the speed of the current and the speed of Carla's boat in still water

Answer 1

c is the current
b is the speed of the boat in still water

rate*time = distance
so
(b-c)*1 = 8
and
(b+c)*1/2 =8

Answer 2

solve the top equation for b and sub.s into the bottom equation to solve for c
once you find c, go back and use it in the first equation to find b
