1. Jacob 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.
