Answer:
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:
[tex]v = \frac{d}{t}[/tex]
From 10A.M. to noon.
You traveled at 50mph during 2 hours. So how long you traveled?
[tex]50 = \frac{d}{2}[/tex]
[tex]d = 50*2[/tex]
[tex]d = 100[/tex]
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.
[tex]v = \frac{d}{t} = \frac{100}{3} = 33.33[/tex]
The average speed over the time interval from 9 A.M. to noon was of 33.33 mph.
