Real-Life Math<br />
This chapter begins by explaining that speed is a relationship<br />
between time <strong>and</strong> distance. The British Eurostar is introduced, <strong>and</strong><br />
it is described as reaching speeds of 186 mph on l<strong>and</strong> <strong>and</strong> 80 mph<br />
in the Chunnel, the tunnel under the English Channel that<br />
connects Britain to France.<br />
Think About It<br />
Do you think it would take the Eurostar longer to travel 160 miles<br />
on l<strong>and</strong> or through the Chunnel? How do you know?<br />
How do you think you could find the distance that the Eurostar<br />
travels on l<strong>and</strong> in 30 minutes?<br />
