Question

Pira drives 825 miles to California. The trip takes him 17 hours. He uses 38 gallons of gas on the trip, which costs him $125. Find is speed. Find is gas mileage. Find the unit price he paid for gas.

Answer 1

Answer:

$Speed = 48.53mph$

$Gas.Mileage = 27.7 mpg$

$Unit.Price = 3.29/gallon$

Step-by-step explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

In order to find the Speed we need to divide the amount of total miles in the trip to California by the amount of time that it took.

$Speed = \frac{Miles}{Hours}$

$Speed = \frac{825.miles}{17.hours}$

$Speed = 48.53mph$

Next we can calculate the Gas Mileage by dividing the amount of total miles  by the amount of gallons of gas that the trip wasted.

$Gas.Mileage = \frac{Miles}{Gallon}$

$Gas.Mileage = \frac{825.miles}{38.gallons}$

$Gas.Mileage = 27.7 mpg$

Finally, we can calculate the Unit Price by dividing the total amount of money wasted in the trip by the amount of gallons used in that trip.

$Unit.Price = \frac{Total}{Gallons}$

$Unit.Price = \frac{125}{38.gallons}$

$Unit.Price = 3.29/gallon$

Answer 2

Speed = Distance /  time:

Speed = 825 miles / 17 hours

Speed = 48.529 miles per hour. (Round the answer as needed).

Gas mileage = miles traveled  / gallons used

Gas mileage = 825 miles / 38 gallons = 21.71 miles per gallon (Round answer as needed).

Unit rate of gas = Total money spend /  gallons bought:

Unit rate of gas = $125 / 38 gallons = $3.289 per gallon.
