Elijah's journey from home to the library is shown on the travel graph below. Calculate his average speed (in mph) for the journey. Round your answer to 1 decimal place.

Answer: 2.7 miles/hour
Step-by-step explanation:
The graph shows Elijaj travelled a total of 3 miles, and took 66 minutes to do it. Covert 66 minutes to 1.1 hours, then divide that into the mileage:
3 miles/(1.1 hours) = 2.7 miles/hr. I assume he was walking. (3 mph is a solid pace).
