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.

Let us assume the upstream rowing rate of Alicia = x

Let us assume the downstream rowing rate of Alicia = y

We already know that

Travelling time = Distance traveled/rowing rate

Then

6 / (x + 3) = 4/x

6x = 4x + 12

6x - 4x = 12

2x = 12

x = 6

Then

Rowing rate of Alicia going upstream = 6 miles per hour

Rowing rate of Alicia going downstream = 9 miles per hour.
