Let’s Begin…
Imagine two aliens racing across outer space to their moon. Who can we deem the fastest alien? With DIRT -- or the equation Distance = Rate x Time -- we can calculate their rates, using the distance they traveled and the time they took. Heather Tunnell explains how to use this helpful equation to determine which of our alien friends is truly faster.
Two friends ride skateboards in opposite directions. The speed of the first skateboarder is 5 miles per hour faster than the second. After 2 hours, they are 70 miles apart. What are their rates?
