A driver travels 30 miles per hour for 3 hours and 25 miles per hour for 4 hours to deliver goods to a town every day from Monday to Saturday. How many miles does the driver travel in a week? Let's think first. Chain of thought:
The driver travels (3 hours * 30 mph) + (25 mph * 4 hours) = 190 miles per day. From Monday to Saturday he travels in total 190 miles / day * 6 days = 1,140 miles in a week.
Therefore, the answer is 1140.
