Late for the Plane
You live in Champaign-Urbana, and you have to catch a plane to Pittsburgh at 9 PM
from Indianapolis airport.
The airport is 117 miles due East from Urbana. But first you have to pick
up your friend Sally in
Watkins, 30 miles West of Urbana.
The weather is lousy, so assume that you drive 50 mph the whole way.
How much before the plane's
departure do you have to leave to make this plane (in minutes) ? (Skip the check-in time.)
T = Minutes
