Question

A car travels at a constant speed. The table shows the distance y (in miles) that the car travels after x minutes. How far does the car travel after 12 minutes? Time (minutes), x 0 10 20 30
Distance (miles), y 0 8 16 24

Answer 1

Answer: 9.6 miles.

Step-by-step explanation:

1. You can calculate the speed of the car with the following formula:

$V=\frac{d}{t}$

Where d is the distance and t is time.

2. Choose any point of the table given in the problem and substitute it into the formula. Then:

(10,8)

Where:

$t=10min\\d=8mi$

So:

$V=\frac{8mi}{10min}=0.8\frac{mi}{min}$

3. Solve for the distance from the formula shown above to calculate the distance the car travels after 12 minutes. as following:

$d=V*t$

4. Substitute values. Then, the result  is:

$d=(0.8\frac{mi}{min})(12min)=9.6mi$
