Question 873271
After 1 1/2 hours.

The car due west is 69 miles away from the gas station (I hope you get it)
The car due south is 48 miles away from the gas station

Therefore, they form a right triangle with their distance from each other as hypotenuse (c):


{{{c^2=a^2+b^2}}}
{{{c^2=(69)^2+(48)^2}}}
{{{c^2=4761+2304}}}
{{{c^2=7065}}}
{{{c=84.054}}} miles

That's letter A.

Hope it helps!
