Question

a taxi charges $2 per mile and $1 per person. If a ride for 2 people costs $12, how many miles was the ride?

Answer 1

5 miles

Explanation:

$12 = ($2 per mile) (2 people)

$12 = $2 + $2m (m = mile)

subtract 2 on both sides to eliminate

$12 - $2 = $2 - $2 + 2m

$10 = 2m

divide both sides by 2 to eleminate m

$10 / 2 = 2m / 2

m = 5
