Math CentralQuandaries & Queries


Question from Christina, a parent:

We ran 3.4 miles in 40 minutes. What was our average speed?

Hi Christina,

In order to answer this you need to know what units of measurement you want for your speed. Is it in miles per hour? miles per minute? feet per second? etc.

Once you know that you simply need to divide the distance (3.4 miles) by the time (40 minutes, 2/3 of an hour, 2400 seconds, etc.)

Hope this helps,
