300 miles at 80 mph would take 3.75 hours.  

Step-by-step explanation: If time is held constant, on the other hand, rather than distance, then the mean speed would be the average. 3 hours at 60 mph followed by 3 hours at 100 mph would yield an average speed of 80 mph. 180 miles, then 300 miles is 480 miles in 6 hours, or 80 mph.

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

0.6

39mph
