Question

how many miles could be traveled in the car on $30 if gasoline cost $2.50 a gallon? a 180 miles b 220 miles c 240 miles d 280 miles

Explanation:

Step1: Find gallons of gas bought

First, we need to find out how many gallons of gas we can buy with $30 when each gallon costs $2.50. We use the formula: number of gallons = total money / cost per gallon. So, number of gallons = $30 / $2.50 per gallon.
\( \frac{30}{2.50} = 12 \) gallons.

Step2: Assume miles per gallon (missing info, but likely 20? Wait, no, maybe the car's miles per gallon is 20? Wait, no, maybe the standard is that if we assume the car gets 20 miles per gallon? Wait, no, maybe the original problem had a miles per gallon, but maybe it's a typo. Wait, no, maybe I missed. Wait, maybe the car's fuel efficiency is 20 miles per gallon? Wait, no, let's check again. Wait, the problem as given: "How many miles could be traveled in the car on $30 if gasoline cost $2.50 a gallon?" Wait, we need the miles per gallon (mpg) of the car. Wait, maybe it's a common problem where the car gets 20 mpg? Wait, no, maybe the problem was supposed to have, like, the car gets 20 miles per gallon. Wait, but since the options are 180, 220, 240, 280. Wait, let's recalculate. Wait, maybe the car's mpg is 20? Wait, no, 12 gallons * 20 mpg = 240 miles. Oh! So maybe the car gets 20 miles per gallon (which is a common mpg, maybe the problem assumes that, or maybe it was a typo and the mpg was 20). So:

Step1: Calculate gallons

Gallons = $30 / $2.50 per gallon = 12 gallons.

Step2: Calculate miles

Miles = gallons mpg. If mpg is 20, then miles = 12 20 = 240 miles. Which is option C.

Answer:

C. 240 miles
