Question

carsons car used 3 gallons of gas to drive 60 miles. fill out a table of equivalent ratios and plot the points on the coordinate axes provided.

gallons | miles
1 |
3 | 60
| 80

Explanation:

Step1: Find miles per gallon

Given 3 gallons for 60 miles, the unit rate (miles per gallon) is $\frac{60}{3} = 20$ miles per gallon. So for 1 gallon, miles = $1\times20 = 20$.

Step2: Find gallons for 80 miles

Let gallons be $x$. Using the rate $\frac{\text{Miles}}{\text{Gallons}} = 20$, we have $\frac{80}{x}=20$. Solving for $x$, multiply both sides by $x$: $80 = 20x$, then divide by 20: $x=\frac{80}{20}=4$.

Answer:

For 1 gallon: 20 miles; For 80 miles: 4 gallons
