A car leaves an intersection traveling west. Its position 10 sec later is 110 ft from the intersection. At the same time, another car leaves the same intersection heading north so that its position t sec later is y= t2 + 3t ft from the intersection. If the speed of the first car 10 sec after leaving the intersection is 21 ft/sec, find the rate at which the distance between the two cars is changing.at.thatinstant of time.

A car leaves an intersection traveling west. Its position 10 sec later is 110 ft from the intersection. At the same time, another car leaves the same intersection heading north so that its position t sec later is y = t² + 3t ft from the intersection. If the speed of the first car 10 sec after leaving the intersection is 21 ft/sec, find the rate at which the distance between the two cars is changing.at.thatinstant of time.
