If a car accelerates from 32.7 km/h to 54.7 km/h in 14.5 s, and the tires have an angular acceleration of 1.639 rad/s2, what is the radius of the tires? Anyone know how to best solve this?

The distance is 2*Pi*R for each revolution of the wheel radius R One revolution is 2*PI radians of angle Acceleration is rateofchange of speed
