To convert 50 miles per hour into miles per minute, we need to determine how many minutes are in one hour.
1. We start with the given expression to convert from miles per hour to miles per minute:
[tex]\[ \frac{50 \text{ miles}}{1 \text{ hour}} \times \frac{1 \text{ hour}}{\square \text{ minutes}} \][/tex]
2. We know there are 60 minutes in 1 hour. Therefore, to convert hours to minutes, we use the value:
[tex]\[ 1 \text{ hour} = 60 \text{ minutes} \][/tex]
3. Substitute 60 for the value in the box (the number of minutes in an hour):
[tex]\[ \frac{50 \text{ miles}}{1 \text{ hour}} \times \frac{1 \text{ hour}}{60 \text{ minutes}} \][/tex]
So, the correct value to be entered in the box is:
[tex]\[
60
\][/tex]
