to be the judge of a space race to their moon.

The only problem is that they are starting

Bleebop is on an asteroid 240 miles from the moon,

Solving this equation is as simple as DIRT.

This stands for distance equals rate times time.

we will only know the distance they traveled

After a few close calls with a wandering satellite,

but let's check out the results with our DIRT equation.

Because we don't know Mark or Bleebop's rate,

Let's set up the same equation for Bleebop and see.

Wow, even though Bleebop got there one hour later,

but with aliens, you can never really tell.

Thanks to DIRT, you now know how to calculate

You don't even need to be watching a space race.

As long as you know two pieces of information

you can calculate any moving vehicle or object.
