Two helicopters leave Springfield, IL at the same time. One travles north at 27 miles per hour and the other travels west at 120 miles per hour. How far apart are they after 3 hrs?
(Hint: Use d=rt to find the distance traveled by each helicopter.)

I know that d=27*3, d=81 and
d=120*3= 360

these are the choices
f. 374 miles
g. 366 miles
h. 369 miles
j. 379 miles
