A boat traveled 240 miles downstream, then 240 miles back upstream. The trip downstream took 20 hours. The trip back upstream to
kotykmax [81]

Answer:

it takes longer for the boat to get back because it's moving against the current. to see how fast the boat is moving, you divide the amount of miles traveled, by how long it took.

240/20 = 12

in still water the boat travels it's 12 miles per hour

240/ 60 = 4

against the current, the boat travels 4 miles per hour

if you need to find the speed of the current, you need to find the resistance that's going against the boat making it slow down. you do that by doing        12 - 4 = 8 miles per hour is the speed of the current.

Step-by-step explanation:

I hope this helps :)
