Selma is flying from Salt Lake City to Washington, DC, a distance of
1,848 miles. Her one-way coach fare is $216. Compute the cost per mile
of her flight.
a. $.12
b. $.09
c. $.15
d. $.18
To calculate the cost per mile of Selma's flight, we divide the total fare by the distance traveled:
$216 ÷ 1,848 miles = $0.117 or approximately $.12 per mile
Therefore, the answer is option a. $.12.
To compute the cost per mile of Selma's flight, we need to divide the total fare by the distance of the flight.
The total fare is $216, and the distance is 1,848 miles.
So, the cost per mile is:
Cost per mile = Total Fare / Distance
Cost per mile = $216 / 1,848 miles
Cost per mile ≈ $0.1169
To round the answer to two decimal places, the cost per mile is approximately $0.12.
Therefore, the correct answer is option a. $.12.
