Question

The tortoise and the hare agree to a race. Of course, they are racing cars, having gotten tired of racing on foot. The tortoise, having just bought a new Mercedes AMG GT, allows the hare to have a running start in his Volkswagen Rabbit. The hare starts the race by getting up to a top speed of 126.2 mph as he passed the tortoise. Just as the hare passes, the tortoise accelerates, at a rate of 7.3 m/s/s.
How far down the road (in meters) does the tortoise catch the hare?
my kinematics equation has too many variables again
