___________________speed__________time____________distance
FIRST______________r______________(____)__________94
SECND______________r-5___________(_____)__________15
Total_____________________________3

Basic rule for uniform rates of travel, RT=D

___________________speed__________time____________distance
FIRST______________r______________94/r____________94
SECND______________r-5___________15/(r-5)_________15
Total_____________________________3

Sum of the times will give the equation to solve for r.
