Question from Terry:

How many seconds would it take to travel 0.18 km at a speed of 130km per hour?

Hi Terry,

The important fact here is that speed is distance over time so you have

\[130 = \frac{0.18}{t}\]

where $t$ is the time in hours. Solve this equation for $t$ and then use that facts that there are 60 minutes in an hour and 60 seconds in a minute to convert $t$ to seconds.
