## Ana and Cristina run two 200

Your pic is too small to read from my device. For others not to strain their eyes, here is the problem.

Ana and Cristina run two 200-meter races. In the first race Ana gives Cristina a start of 20 meters and beats her by 5 seconds. In the second race Ana gives Cristina a start of 8 seconds and beats her by 8 meters. Find the rate of Ana.
