Question

A motorboat can go 8 miles downstream on a river in 20 minutes. To travel the same 8 miles upstream, the boat takes 30 minutes. Find the speed of the current.

Answer 1

I think you have to find speed in both cases and the difference will be the speed of the current:
V1 = 8/20
V2 = 8/30
V = |V1-V2|

Answer 2

i have an equation set up but can u review it?

Answer 3

sure post it

Answer 4

20r+20c=8 and 30r-30c=6

Answer 5

=8 not 6

Answer 6

Do you still need help

Answer 7

so what are u solving for, and i have no idea what those equations mean..

Answer 8

I think you can turn it into relative velocity problem

Answer 9

r= rate c=current

Answer 10

solve for currren...question is at the top

Answer 11

River speed+Boat Speed= Actual Speed

Answer 12

River speed we denote x for downstream -x for upstream

Answer 13

i need it done by the eqution i have set up
