1. 7mph;

2. 7mph

3. Stayed thesame

Step-by-step explanation:

Average speed = Distance/Time

1. What was his average speed from hour 2 to hour 4?

Speed = Distance/Time

Speed = (27.5 - 13.5)/(4 - 2)

Speed = (14/2)

Speed = 7mph

2. What was his average speed from hour 4 to hour 7?

Speed = Distance/Time

Speed = (48.5 - 27.5)/(7-4)

Speed = (21/3)

Speed = 7mph

3. Since the speed are thesame, he stayed thesame.
