Distance Between Two Cars A car leaves an intersection traveling west. Its position 4 sec later is 19 ft from the intersection. At the same time, another car leaves the same intersection heading north so that its position 4 sec later is 29 ft from the intersection. If the speeds of the cars at that instant of time are 8 ft/sec and 14 ft/sec, respectively, find the rate at which the distance between the two cars is changing. (Round your answer to one decimal place.)

74y - 8 - 78y = -4y - 81.) group them: 74y - 78y - 8 = -4y - 82.) simplify: -4y - 8 = -4y - 83.) add -4y and 8 to both sides0 = 04.) answer: no solutionhope this !   ~shane
