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.

Question

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|

bahrom7893 · Answer

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

anonymous · Answer

I think you can turn it into relative velocity problem

mathhelp · Answer

r= rate c=current

mathhelp · Answer

solve for currren...question is at the top
