Q. Christopher's car can hold 17 gallons of gas. The given table shows the amount of gas used by the car based on the number of hours it travels. Which of the following statements is correct and how many gallons of gas will be used if the car travels for 8 hours?

$\begin{array}{ccccc}\text{Time (hours)}& 1& 2& 3& 4\\ \text{Quantity of gas}& 2& 4& & \\ \text{used (gallons)}& & & & \end{array}$

2. Quantity of gas used (in gal) is half the travel time (in h). So, 4 gal will be used in 8 h.
3. Quantity of gas used (in gal) is one more than the travel time (in h). So, 9 gal will be used in 8 h.
4. Quantity of gas used (in gal) is twice the travel time (in h). So, 16 gal will be used in 8 h.
