A)
The difference between these two is that one is miles and one is min. And if you look closely you can see as every mile goes its equal to 7 so the equation would be 7min=1 mi
B)
The rate of change would be 7 so as you see 1x7 is 7, 3x7 is 21, and 5x7 is 35 so each mile equals 7 minutes.
C)
If Mario ran for 70 minutes he would’ve ran for 7 miles because 7x10 is 70
I really hope this helps and have a good one. By any chance do you think you could give me BRAINLIEST
