Question

If you run 3 meters per second to the left, where will you be 4 seconds after you pass zero?

Answer 1

12 meters to the left of your starting point.

Explanation:

You start at 0 meters. You then start running to the left with an acceleration of 3 m/s to the left. After each seconds, you are 3 more meters to the left.

So

3 m/s * 4 s = 12 m to the left.

Hence, the answer in 12 meters to the left.

Answer 2

12 meters to the left, or -12

Explanation:

3 meters per second for 4 seconds

Meaning it's 3 x 4

3 x 4 = 12, so therefore it's -12 meters or just 12 meters to the left.
