Rita traveled 135 miles in 4 fewer hrs than it took Jean to traveled 945 miles. If jeans speed was 3 times that of rita what was the speed of rita?

Not really chemistry!
If the speed of Jean is J mph and the speed of Rita is R mph then we can write 3 equations where t=time(hrs) taken by Jean.
Jxt=945
R(t4)=135
J=3R
and solve for R
