Leadfoot Lilly was driving miles per hour when she passed a parked highway patrol car. By the time she was half a mile past the spot where the patrol car was parked, the officer was driving after her at miles per hour. If these rates remain constant, how long will it take the officer to catch up to Lilly? Write and solve an equation to represent this situation.

This is a distance, rate, and time problem.
Set up a table with the known values.

If time = t:



Set up the two equations and solve for .
