Answer

Upon performing the division, we arrive a numerical approximation for runner's speed: approximately \(4.38 \: meters/second\). Rounded off to two decimal points. <br /><br />So the average speed is roughly \(4.38 \: m/s\).

Explain

## Step1:<br />Firstly, we will convert the total time in which the runner completed the race from minutes and seconds into total seconds. As one minute contains 60 seconds, 2 minute 17 seconds can be converted into seconds through the formula: \(2 \times 60 + 17 = 137\) seconds<br /><br />## Step2:<br />Coming off of that, we can now use the given formula for average speed ( S = D ÷ T) where:<br /><br />S = average speed,<br />D – distance covered by runner,<br />T – time taken to achieve this.<br /><br />Substituting the obtained time (137 seconds) and the given distance (600 meters), the formula becomes: \(S = \frac{600}{137}\)
