Given:
Nancy is running 3 meters per second.
Juan starts the same race 3 meters ahead of Nancy but he is going at 2 meters per second.
To find:
The equations for Nancy and Juan.
Solution:
Let x be the number of seconds.
Nancy is running 3 meters per second. So, the total distance covered by Nancy in the race is
![y=3x](https://tex.z-dn.net/?f=y%3D3x)
Juan starts the same race 3 meters ahead of Nancy but he is going at 2 meters per second. So, the total distance covered by Juan in the race is
![y=3+2x](https://tex.z-dn.net/?f=y%3D3%2B2x)
Therefore, the equations of Nancy and Juan are
and
respectively.
