Speed Conversion and Time Calculation
<p>To convert speed from kilometers per hour (km/h) to kilometers per minute (km/min), divide the speed by 60, since there are 60 minutes in one hour.</p>
<p>Let \( v \) represent the speed in km/h and \( v' \) represent the converted speed in km/min.</p>
<p>\( v' = \frac{v}{60} \)</p>
<p>Next, to find the distance covered in 42 minutes, multiply the converted speed by the time in minutes.</p>
<p>Let \( d \) represent the distance covered in kilometers.</p>
<p>\( d = v' \cdot 42 \)</p>
<p>Substitute \( v' \) from the first equation:</p>
<p>\( d = \frac{v}{60} \cdot 42 \)</p>
