That's the wrong question. Tank size does not determine fuel consumption. The only way to ACCURATELY determine fuel consumption is to fill the tank, drive as far as you dare on that tank of fuel, fill the tank again then calculate the mileage by the following:
Divide total miles driven on that tank of fuel by the number of gallons used.
M/G=MPG
Where:
M=miles driven on that tank of fuel
G=number of gallons required to REFILL the tank after driving those miles
MPG=miles per gallon

143 miles-229 kilometers
143 miles = 230 km.

143 miles is 230.14 kilometers.
Depends on what you are paying per gallon for fuel. 6,000 divided by 42 equals 142.85. So you know you will use at least 143 gallons of fuel. Assuming you will pay on average $3.60 for fuel it will cost you, 143 x $3.60 = $514.80.
143/55 or 2 h 36 m.
88.85608 miles per hour
These are two separate things.
