Question

If your car gets 26 miles per​ gallon, how much does it cost to drive 430 miles when gasoline costs ​$3.00 per​ gallon?

Answer 1

$51

Explanation:

To solve this, we must divide the total amount of miles by the miles per gallon, and multiply that by the cost per gallon.

430 / 26 = 16.53

Because this is talking about gallons, we should round up to 17.

17 * 3 = 51

It costs $51 to drive 430 miles when gasoline costs $3 per gallon.

Answer 2

$49.62

Explanation:

We know that the car travels for 26 miles in 1 gallon. So we will find out the number of gallons it requires to travel for 430 miles by simple ratio method.

`(1 gallon)/(x) =(26 miles)/(430)`

`x=(430)/(26)`

`x=16.54`

Now that we know that the car needs 16.54 gallons of gasoline to drive for 430 miles, we can simply multiply the number of gallons by the cost per gallon to find its total cost.

Total cost of gasoline to drive 430 miles = 16.54 x 3 = $49.62
