Question

Mindy is training to run a marathon. She runs 4 miles each day. Write an equation that would represent the number of miles m, she runs on a given day, d.

Answer 1

You know that she runs 4 miles every day, so we can set up the equation:

$\sf m=4d$

For any given day you just plug that number in for 'd' and it will give you the total number of miles.
