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.

Explanation:

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

`V=(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=(8mi)/(10min)=0.8(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(mi)/(min))(12min)=9.6mi`
