"DISTANCE BETWEEN TWO CARS A car leaves an intersection traveling west. Its position 4 sec later is 20 ft from the intersection. At the same time, another car leaves the same intersection heading north so that its position t sec later is t² + 2t ft from the intersection. If the speed of the first car 4 sec after leaving the intersection is 9 ft /sec, find the rate at which the distance between the two cars is changing at that instant of time."
