1. Jack set out from Pottstown one morning to drive to Peoria, where he had a business appointment. Presently he figured that he would be late if he did not speed up. He had been on the road for 36 minutes, averaging 30 miles per hour. At that rate, he would be 16 minutes late for his appointment. So he stepped on the gas, and by averaging 35 miles per hour for the rest of the trip he just made Peoria in time. How far is it from Pottstown to Peoria?
