ONE DAY
rate      time      distance
x         24/x        24
y         40/y        40
Total      9

NEXT DAY
rate       time      distance
x          18/x       18
y          48/y       48
Total       9



The time expressions are filled according to ;

.

The two time sum relationships for the two days give the system


You can solve that system, ... unless you need help with the algebra or arithmetic steps.
