Juan drove from Portland to Ashland on Interstate 5, then from Ashland to Klamath Falls on Highway 66. Assume that I-5 goes directly south and Highway 66 goes directly east. It is 280 miles from Portland to Ashland and 64 miles from Ashland to Klamath Falls. How many total miles did Juan travel? If a road was built directly from Portland to Klamath Falls, how long would it be? Round your answer to the nearest mile. Approximately how much shorter would Juanβs trip be if he was able to take the direct route.
