A policeman is positioned on a highway without a radar gun. He knows the distance fromthe construction zone to an exit is a quarter mile, and the speed limit is 60 mph. He timesa car taking 10 seconds to go the quarter mile. He times a truck taking 12 seconds to gothe quarter mile. Could he ticket them for speeding? Given that a car’s distance in feet east of an intersection t seconds since it started movingis represented by d = t2 −2t, determine the car’s average speed over each interval of elapsedtime.(a) t1 = 2 to t2 = 6(b) t1 = 6 to t2 = 10(c) t1 = 10 to t2 = 11(d) What observations can you make about how the car’s speed is changing on the timeinterval from t1 = 2 to t2 = 11 since the car started moving east of the intersection.
