How many feet in 400 yards?

[MATH]x\text{ yd}=x\text{ yd}\cdot\frac{3\text{ ft}}{1\text{ yd}}=3x\text{ ft}[/MATH]
Hence:

[MATH]400\text{ yd}=3(400)\text{ ft}=1200\text{ ft}[/MATH]

More conversion factors.

In problems like this, it's kind of trivial, but when you're doing physics problems it becomes a highly useful technique for converting units that include many fundamental units, making it easier to get everything correct, and not get mired down.

It is definitely a useful skill.

This is found with the same procedure used in chemistry most of the time.
