T took Anthony's family 5 hours and 10 minutes to drive the 296 miles between Chicago and St. Louis. What was their average speed, in miles per hour?

57.4 mph

Step-by-step explanation:

The process will be to divide the number of miles by the amount of time

So,

miles = 296

time = 5 hr 10 min

miles / time

296 / 5 hr 10 min

re-write 5 hr 10 min as 5.16

296 / 5.16

57.4 mph on average
