Word problem: He left at 8:20 AM and arrived at 2:40 PM after driving for 335 miles. What was his average speed in miles per hour?

Respuesta :

There's 6 hours and twenty minutes between 8:20 and 2:40, which means you would divide 335 mi by 6.2 hrs. Thats gets you the answer of 54 mph (54.03 to be exact.) Hope that helps!
