Answer:
<h3>
B.</h3>
Step-by-step explanation:
The distance between two any points <em>a</em> i <em>b</em> is |a-b| as we don't know which of them is larger number.
So:
a=-2 and b=1 means distance |-2-1| = |-3| = 3
{If we know the value of given points we can subtract the smaller one from the larger. It also works: -2<1, so the distance would be 2-(-1)=2+1=3}
$291-$210=$81
$81/0.15= 540 miles
I believe the answer is 540 mi.
