Answer:
C
Step-by-step explanation:
It just says the difference between “a number” and 12. For an expression it has to have numbers grouped together
Set up a proportion:
17 miles in 306 minutes, write as 17/306
X miles in 162 minutes, write as X/162
Now set to equal and solve:
17/306 = x/162
Cross multiply:
17 * 162 = 306 *x
2754 = 306x
Divide both sides by 306:
x = 2754 / 306
x = 9
It will travel 9 nautical miles.
