Aman once had to go by bicycle twelve miles to the railroad station to catch a train. he
thought: 'i have an hour and a half to catch the train. four miles is uphill, four miles are
downhill, and four miles is level road. i can go uphill at 4 miles per hour, downhill at 12
miles per hour, and i can go 8 miles per hour on level road. this is an average of 8 miles per
hour, so i'll get there in time.' was his reasoning correct? why or why not?
