A driver accelerates when the car is traveling at a speed of 30 miles per hour (i.e., 44 feet per second). The velocity (in feet per second) function is v(t) = 44 + 2.2t. The car reaches the speed of 60 miles per hour (i.e., 88 feet per second) in 20 seconds. Then, during the 20 seconds, the car has traveled miles.
