Let x be Chloe's biking speed in mph; then Jason's speed is x+6.

At 2pm, Chloe has been riding for 4 hours and Jason has been riding for 1.

4 hours at x mph, plus 1 hour at (x+6) mph, equals a total distance of 66 miles:

Solve using basic algebra.

Then remember the solution to the equation is x, which is Chloe's speed. The answers to the problem are x and x+6.
