[SPLIT] A bicyclist rode into the country for 5 hours...

[Takitia]

is this correct?

A bicyclist rode into the country for 5h. In returning, her
speed was 5mi/h faster and the trip took 4 h. Waht was her
speed each way?

d=r.t
5hx5mi/hx4h

 

[galactus]

The distance is the same each way, therefore, we have the equation:

d=rt

\(\displaystyle \L\\5r=4(r+5)\)

Solve for r.
