A bicyclist rode into the country for 5 h. In retruning her speed was 5 mi/h faster and the trip took 4 h.?

Question:what was her speed each way?
how do i set this up??
thanks

Answers:
Distance = speed x time
Since each way has equal distance then the equation should be like this:
5(s) = 4(s + 5)
5s = 4s + 20
s=20

The speed into the country was 20mi/h and her returning speed was 25mi/h..

hope this helps..
M(X+X+5)=H
m= miles traveled
x = speed outgoing
H=hours traveling=4
