The average speed over the time interval from 9 A.M. to noon was of 33.33 mph.
Step-by-step explanation:
The average speed is given by the following equation:

From 10A.M. to noon.
You traveled at 50mph during 2 hours. So how long you traveled?



You traveled 100 miles.
What was your average speed over the time interval from 9 A.M. to noon
From 9 A.M. to 10 A.M, you did not travel.
From 10 P.M. to noon, 100 miles.
So 100 miles during 3 hours.

The average speed over the time interval from 9 A.M. to noon was of 33.33 mph.
