Acar leaves an intersection traveling west. its position 4 sec later is 21 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 13 ft/sec, respectively, find the rate at which the distance between the two cars is changing.
