Answer: Fourth option is correct.
Step-by-step explanation:
Since we have given that
thirty miles over three gallons
Unit rate would be [tex]\dfrac{30}{3}=10[/tex] miles per gallon.
three gallons over thirty miles
Unit rate would be [tex]\dfrac{3}{30}=0.1[/tex] miles per gallon.
four gallons over sixty miles
Unit rate would be [tex]\dfrac{4}{60}=0.67[/tex] miles per gallon.
sixty miles over four gallons
Unit rate would be [tex]\dfrac{60}{4}=15[/tex] miles per gallon.
Hence, Fourth option is correct.
