Final answer:
Marcus drives an additional 4.464 miles per hour compared to Anthony. Marcus's speed is 54.6 mph while Anthony's speed is 50.136 mph.
Step-by-step explanation:
To calculate how many more miles Marcus drives in 1 hour compared to Anthony, we first need to determine each person's driving speed in miles per hour (mph).
Marcus drove 354.9 miles in 6.5 hours. To find his speed, we divide the total miles by the total hours: 354.9 miles ÷ 6.5 hours = 54.6 mph.
Anthony drove 250.68 miles in 5 hours. His speed is calculated as 250.68 miles ÷ 5 hours = 50.136 mph.
To find out how many more miles Marcus drives in 1 hour, subtract Anthony's speed from Marcus's speed: 54.6 mph - 50.136 mph = 4.464 mph. So, Marcus drives an additional 4.464 miles in 1 hour compared to Anthony.
