Me and my friend are going on a trip to Nashville TN next month.

we found a cheap hotel for around 50 bucks. We need someone to be very kind to calculate how much gas it would take to get there and back. please leave your resources. we are going to be driving a 2009 Nissan Rouge. We are driving from chesapeake ohio and it is approximately 285 miles away from Nashville. If anyone knows how much gas that would be please let us know. Also, if anyone knows how much money we should bring for food..for 3 people and we are staying for 1 day. thanks
