If you travel at maximum speed of 6 mph upstream with a river current of 2 mph, how far will it travel in 6 hours?

Question

The assignment is on quadratic equations.

Answer 1

travel maximum speed up stream at 6 mph

with current speed = 2 mph

net speed 6-2 = 4 mph upstream

in 6 hours you go 6x4 = 24 miles

or

6x6 -2x6 =36-12 = 24 miles
