You can put this solution on YOUR website! bob is traveling in a canoe that can go downstream at 6 km/h and upstream at 2 km/h. If she starts upstream and wishes to return to the starting point in exactly 4 hours. How far should he travel upstream?
***
let x=hours Bob travels upstream
4-x=hours Bob travels downstream
distance=speed*travel time
2x=6(4-x)
2x=24-6x
8x=24
x=3
2x=6
How far should he travel upstream? 6 km
