Calculating distance given speed and time
Example
Iain walked from his parents' farm into town at a steady speed of \(5\,km/h\).
The journey took \(3\;hours\). How far did Iain walk?
In the first hour he walked
After two hours he had walked \(10\,km\).
After three hours he had walked \(15\,km\).
\(Distance = Speed \times Time\)
\(Distance = 5 \times 3\)
\(Distance = 15\,km\)
Now you can try this example.
Question
Shona cycles at an average speed of \(8\,km/h\). How far has she travelled if she cycles for \(4\;hours\)?
\(Distance = Speed \times Time\)
\(Distance = 8 \times 4\)
\(Distance = 32\,km\)
Shona has travelled \(32\,km\).
