Question 517244: A car leaves an intersection traveling east. Its position t sec later is given by
x = t^2 + t
ft. At the same time, another car leaves the same intersection heading north, traveling
y = t^2 + 3t ft
in t sec. Find the rate at which the distance between the two cars will be changing 3 sec later.?

-----------
=
--------------
d'(t) =
d'(3) = (216 + 216 + 60)/(2(162 + 216 + 90))
= 492/936
= 41/78 ft/sec
