# Focus On the Units

Watch the video. Then read the problem below.

Emma has been running laps around the track. (A lap is a quarter mile.) Her coach recorded how many minutes she ran. After Emma’s run, her coach wrote these calculations on his clipboard:

30 ÷ 15 = 2 and 15 ÷ 30 = 0.5

The coach forgot to include the units with his calculations.

- Determine what the numbers mean. Explain your thinking.
