Answer

Therefore, the postal worker could travel \( 720 \, \mathrm{m} \).

Explain

##Step 1: <br />First, we need to convert the total traveled time from minutes into seconds, as the speed provided is in m/s. One minute corresponds to 60 seconds, hence three minutes correspond to \(3 \times 60 = 180 \) seconds.<br /><br />##Step 2:<br />Next, using the formula of distance which is the multiplication of speed and time travelled, it's: \( \text{distanceine (m)} = \text{speed (m/s)} \times \text{time (s)} \).<br /> <br />###\( \text{distance} = \text{speed} \times \text{time} \)<br /><br />##Step 3:<br />Plug in the values:<br />Given that the speed is \( 4 \, \mathrm{m} / \mathrm{s} \) and time taken, having converted the minutes to seconds is \( 180 \, \mathrm{~seconds} \), therefore,<br /><br />###\( \text{distance} = 4 \, \mathrm{m}/\mathrm{s} \times 180 \, \mathrm{s} \)<br /><br />And performing the calculation gives:<br /><br />###\( \text{distance} = 720 \, \mathrm{m}\)
