That depends a great deal on the vehicle you are driving, the terrain you are driving over and your personal driving habits. If you are driving a gas guzzler over rough, uphill terrain with lots of gunning of the engine you might only be able to go 50 or 60 miles on 8 gallons. If you are driving a hybrid car on smooth roads in good weather you might get more than 400 miles on 8 gallons. I've driven a pickup under the described conditions and got the stated mileage. I've also driven a hybrid vehicle and that regularly got the stated 400+ miles using only 8 gallons.
If a car can go 150 miles on 5 gallons then it will travel 600 miles on 20 gallons of gas
About 131 gallons.
If you go 393 miles on 9.770 gallons of gas, then you are getting 393/9.770 or about 40.2 miles/gallon
1500/28 = 53.57 gallons.
3,000/26 = 115.385 gallons (rounded)
Basic mental arithmetic !... 52.85 gallons.

175 miles= 12 gallons therefore 43.75 miles=3 gallons multiply that by 6 262.5 miles= 18 gallons answer is 262.5
870 miles divided by 22 miles per gallon =gallons 870/22 = 39.5 gallons
16.04
It depends on your gas millage. So, it depends on what you are driving. It could be 14 gallons could be 80 gallons.
175 miles on 7 gallons implies 175/7 = 25 miles per gallon. So with 15 gallons it will go 15*25 = 375 miles.
