Question

*** i will give you a medal ***
Alicia can row 6 miles downstream in the same time it takes her to row 4 miles upstream. She rows downstream 3 miles/hour faster than she rows upstream. Find Alicia’s rowing rate each way. Round your answers to the nearest tenth, if necessary.

Answer 2

let x be the speed of boat, y be the speed of stream
Alicia can row 6 miles downstream in the same time it takes her to row 4 miles upstream.
=> 6/(x+y) = 4(x-y).............equation #1
She rows downstream 3 miles/hour faster than she rows upstream.
=>(x+y)-(x-y) = 3 => y = 1.5................#2
solving, x = 7.5
so,
x+y = 9
x-y = 6
D- 9 mi/h downstream, 6 mi/h upstream
