Answer:

B. 60

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 =
50* (1)/(60)

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.
