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.

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
