distance problem

Question

Alicia can row 7 miles downstream in the same time it takes her to row 4 miles
upstream. She rows downstream 4 miles/hour faster than she rows upstream.
Find Alicia’s rowing rate each way. Round your answers to the nearest tenth, if
necessary

Answer 1

7/x=4/(x-4)

x=9.3333 down speed

x-4=5.333 up speed
