Final answer:
The correct option is A, which shows the proportional relationship between the time and the number of snowballs made, using the unit rate of 12 snowballs per minute.
Step-by-step explanation:
To solve the given problem, we need to establish the rate at which snowballs are made. As per the information provided, in 1 minute, 12 snowballs were made. This is the constant rate since the number of snowballs made in any given time is directly proportional to the time spent making them. Let's first find the number of snowballs per minute (the unit rate).
The table should reflect this constant rate. We will calculate the number of snowballs made in different time frames by multiplying the unit rate by the number of minutes.
If 12 snowballs are made in 1 minute, then in 4 minutes, 4 times 12 snowballs, which equals 48 snowballs, are made. Now, let's apply this rate to option A which is the correct one:
- Time (1 minute) = 12 snowballs
- Time (4 minutes) = 12 snowballs * 4 = 48 snowballs
- Time (5 minutes) = 12 snowballs * 5 = 60 snowballs
All other options provide an incorrect relationship between time and the number of snowballs.
