Answer:
unit cost in dollars per mile
Step-by-step explanation:
You are given cost, miles, and time for a certain trip.
You are asked the cost for a certain number of miles, so you need a unit cost of dollars per mile.
$7.20/(12 miles) = $0.60/mile
$0.60/mile * 46 miles = $27.60
By first finding the unit cost per mile, you can then find the cost of the 46-mile trip.
Answer:
0.40, mile
Step-by-step explanation:
because you had to multiply to get the total cost and then divide the number by the total cost.
