9 + 10=21 :)
9=3 x3
10= 2 x 5
3x5=15
3x2=6
15 + 6 = 21 :)
I think it would be easier to covert the fractions to decimals here
-1.2 * 1 1/5 / 3/10
= -1.2 * 1.2 / 0.3
= -1.44 / 0.3
= - 4.8 answer
Make two equations from the information. Then graph them and see where they intersect. The answer is 62 miles. Plug 62 back into both equations and they should both be the same number.
PICTURE1: They are both 45
PICTURE2: 810
