Answer:
less than 27 m/s
Explanation:
The average speed would be total distance (10 + 10 = 20 miles = 32000 m) over total time
The time it takes you to drive the first 10 miles (16000 m) at 24m/s is
16000 / 24 = 666.67 s
The time it takes you to drive the 2nd 10 miles (16000 m) at 30 m/s is
16000 / 30 = 533.33 s
The average speed is
[tex]v = \frac{16000 + 16000}{666.67 + 533.33} = \frac{32000}{1200} = 26.67 m/s[/tex] < 27 m/s
So your average speed is less than 27 m/s
