From another answer, "There are various methods to calculate this. One approach is:
With a range of 400 miles on a 15-gallon fuel tank,
400 / 15 results in 26.66666666666667 miles for every gallon (it seems odd, but we'll reach a concise outcome shortly)
Thus, 26.66666666666667 multiplied by 6 gallons equals 160 miles.
<span>Final result: Landon's SUV can go </span>160 miles<span> using 6 gallons."</span><span />
