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 4 sec later is 28 ft from the intersection. If the speeds of the cars at that instant of time are 9 ft / sec and 11 ft / sec, respectively, find the rate at which the distance between the two cars is changing. | Numerade
