Answer 1

The value that can be entered in the box to correctly convert 50 miles per hour to miles per minute is 60.

Step-by-step explanation:

The value that can be entered in the box to correctly convert 50 miles per hour to miles per minute is 60.

To convert miles per hour to miles per minute, we need to multiply by the conversion factor that cancels out the hour and leaves only minutes. As there are 60 minutes in an hour, we multiply 50 miles/hour by 1 hour/60 minutes. This gives us a conversion of 50 miles/hour * 1 hour/60 minutes = 50/60 miles/minute = 5/6 miles/minute. In decimal form, this is approximately 0.833 miles/minute.

Therefore, the value that can be entered in the box to correctly make this conversion is 60.
