G can be on the left or right of E. If it’s on the left it is at point 2-13=-11, and if it’s on the right it is at point 2+13=15. So the two possible positions for G are -11 and 15.
The probability that the card chosen will not be green is 5/7
28.95 is 14.7 greater than 14.25
18 / 1 = x / 15......18 miles to 1 gallon = x miles to 15 gallon
cross multiply
(1)(x) = (18)(15)
x = 270 miles
