Answer:
C
Step-by-step explanation:
The money has to be either less than or equal to $50, since the sentence says each lunch that means that's the cost for a lunch for each friend, and the $4 dessert is an item that costs money, therefore adding the cost to the lunch.
12 x 40 = 480 feet per minute.
480 x 60 = 28800 feet per hour.
28800/5280 = 5.45 miles per hour.
