10 20 40 80 160 320 640
1280 2560 5120 10240 20480 40960 81920
81920/5280 = 15.51515151, rounded to the nearest tenth of a mile, 15.5 miles
Question b asks for how many miles in total has he ran. That means we have to add each of the values shown above and that equals to 163830 feet.
Divide that by 5280 and that equals 31.02 miles, rounded to the nearest tenth, 31 miles.
The answer is -4,0 4,8 because u would solve for one variable in one of the equations and then substitute the result into the other
It is 8.525. what u do is 21÷40 and get .525 and then u add the 8 in the front and get 8.525
