Jen motorboat travels at a speed of 13mph in still water. booth river flows at a speed of 3mph. how long will it take jen to travel 11 mi upstream? 11mi downstream

Upstream 1.1 hours and down stream 0.6875 hours.

Step-by-step explanation:

Jen motorboat travels at a speed of 13 mph in still water.

Now, the speed of river flows is 3 mph.

Therefore, the upstream speed of the boat is (13 - 3) = 10 mph and the downstream speed of the boat will be (13 + 3) = 16 mph.

Therefore, to travel 11 miles upstream Jen will take hours.

And to travel 11 miles down stream Jen will take hours. (Answer)
