At noon the armadillo left the wild Kingdom and headed north at 3 km/h. two hours later the raccoon left the same kingdom and headed south at 5 km/h. at what time will the animals be 38 km apart?
the arm has a 2 hr headstart 3 km/hr x 2 hr = 6 km before racoon sets out
then the two critters are separating at 3 + 5 = 8 km / hr
6 km + 8km/hr * x hr = 38 km
x= 4 hr after the racoon left or 6 hours after the arm left noon + 6hr = 1800 or 6 pm
