Lisa left camp on her bicycle at noon and rode at an average rate of 10 miles per hour. Morton left camp in his van at 1:30 p.m. and over took Lisa in 30 minutes. At what average rate was he traveling in the van?
-----------
Morton overtook Lisa 2 hours after she left (1:30 + 1/2 hour).
At 10 mph, Lisa traveled 20 miles.
Morton traveled 20 miles in 1/2 hour --> 40 mph.
