Mike fills his car's gas tank up with 20 gallons of regular gas at $2.09 per gallon. His car averages 25 miles per gallon. How much does it cost Mike to drive per hour?

Thank you for the opportunity to help you with your question!

Mike pays 20 x $2.09 = $41.80 to fill up his tank

With 20 gallons he can drive 20 x 25 = 500 miles per tank of gas

Since the question does not provide information on Mike's speed or how long it takes him to reach his destination, we cannot determine the cost per hour.

Please let me know if you need any clarification. I'm always happy to answer your questions.
