Answer :
There are few ways to count it. One of them is:
400 miles on 15-gallon tank
400 / 15 = 26,66666666666667 miles per 1 gallon (looks weirdly but we'll get a nice result in a second)
So 26,66666666666667 * 6 gallons = 160 miles
Answer: Landon's SUV can travel 160 miles on 6 gallons.
400 miles on 15-gallon tank

Answer: Landon's SUV can travel 160 miles on 6 gallons.
we know that
by proportion
[tex]\frac{400}{15}\frac{miles}{gallons}=\frac{x}{6}\frac{miles}{gallons}\\ \\15*x=6*400\\ \\x=(6*400)/15\\ \\x=160\ miles[/tex]
therefore
the answer is
[tex]160\ miles[/tex]
