Problema Solution
alicia can row 4 miles downstream in the same time it takes her to row 2 miles upstream. she rows downstream 4 miles/hour faster than she rows upstream. Find Alicia's rowing rate each way
Answer provided by our tutors
Let x=Alicia's upstream rowing rate
x+4=Alicia's downstream rowing rate
Travel time= distance/rowing rate
4/(x+4)=2/x
4x=2x+8
2x=8
x=8/2=4 mph upstream Rate
x+4=6 mph downstream Rate
