126/10 would mean that from the original number, the decimal point is at 126.0 so when it is divided by 10, it will move over one placement, making it 12.6... I would estimate that your answer is C. 12.6
As i see it
It’s pretty forward, logically only A is possible
If the Earth were a flat surface, then 9 miles east and 12 miles north would be
the basis of a right triangle, and the straight-line route would be the hypotenuse.
We could use the Pythagorean Theorem to find the straight-line distance.
A² + B² = C²
C² = (9)² + (12)²
C² = 81 + 144
C² = 225
C = √225 = <u>15 miles</u>
That's Choice-'H'.
