With t in hours, at t = 0 Dale entered Highway 1. At t = 2 he was 126 miles down the highway, on the side of the road with a flat tire. At t = 3 he was still on the side of the road, waiting for road assistance. What was Dale’s average velocity over each of the time intervals:
(a) From t = 0 to t = 2
(b) From t = 0 to t = 3
(c) From t = 2 to t = 3
