You are driving down the road when you see a deer in your headlights. It takes you 0.5 seconds to react. Once you react you start braking, and you decelerate at 3m/s2. The skid marks on the road are 120 meters long, and you somehow manage to stop just before hitting the deer (so Bambi's mother gets away safely).

What was your speed before you hit the brakes?
