A kayaker paddles upstream for 1.5 hours then turns kayak around and return says can't say in one hour he travels 3 miles each way what is the rate of the current and what is the kayakers rate in still water

72 is the answer to this problem

24

step-by-step explanation:

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
