Answer:
B. 60
Step-by-step explanation:
Here, the given phrase,
50 miles per hour,
⇒ Number of miles in 1 hour = 50
⇒ Number of miles in 60 minutes = 50 ( ∵ 1 hour = 60 minutes )
⇒ Number of miles in 1 minutes = [tex]50\times \frac{1}{60}[/tex]
Hence, if the expression to convert 50 miles per hour to miles per minute is,
50 mile/1 hour•1 hour/_minutes,
Then missing value in the expression would 60.
Option 'B' is correct.
