Calculate the average speed for each time interval given in the following table. Simplify answers.

The distance traveled on a 3-hour trip is recorded every half-hour in the table below. Distance Traveled Time in Hours 0 0.5 1 1.5 2 2.5 3 Distance in Miles O 35 60 110 140 170 190 Time t = 0.5 to t = 1 s(1) - s(0.5) 1 - 0.5 = = mph 0.5 t = 0.5 to t = 1.5 s(1.5) - s(0.5) = 1.5 - 0.5 S mph 1 t = 1 to t = 2 s(2) - s(1) 2-1 mph t = 1 to t = 3 s(3) - s(1) = = 3 -1 mph 2
