Question - Speed Conversion and Time Calculation

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.

Let \( v \) represent the speed in km/h and \( v' \) represent the converted speed in km/min.

\( v' = \frac{v}{60} \)

Next, to find the distance covered in 42 minutes, multiply the converted speed by the time in minutes.

Let \( d \) represent the distance covered in kilometers.

\( d = v' \cdot 42 \)

Substitute \( v' \) from the first equation:

\( d = \frac{v}{60} \cdot 42 \)
