20 and 10, 20 is 2 times 10 and if you add them together its 30
M2 is 180-97.54 which equals 102.46
D. 7 miles
Step-by-step explanation:
26.5/4 =6.62
So the best estimate is 7 miles
You put it in a calculator and you get 97.06349206.
I think it could 78 because well i dont think it is right but try if you take away 10 from 16 you would get 6 then if you add 20 to 68 you would get 88 and if you you take away 100 from 88 you would get the 78 and then you would add 20 so you would get 98
