Answer :
Answer: Colin can make approximately 30 drinks during his 90-minute shift.
Step-by-step explanation:
We can find out how many drinks Colin can make in 90 minutes by figuring out how his drink-making rate translates from minutes per drink to drinks per minute. Here's how:
Step 1: Calculate Colin's drink-making rate per minute
We know Colin makes 4 drinks in 12 minutes.To find the rate per minute, we divide the number of drinks by the time it takes:
Drinks per minute = Drinks / Time (minutes)
Drinks per minute = 4 drinks / 12 minutes
Drinks per minute = 1/3 drinks per minute
(This means Colin can make 1/3 of a drink every minute on average).
Step 2: Calculate the total work time in minutes
Colin's shift is 90 minutes long.
Step 3: Find the total number of drinks made
Now that we know Colin's drink-making rate (1/3 drinks per minute) and his total work time (90 minutes), we can multiply them to find the total number of drinks:
Total drinks = Drinks per minute * Total work time (minutes)
Total drinks = (1/3 drinks/minute) * 90 minutes
Total drinks = 30 drinks
Note: This calculation assumes a constant rate of drink-making throughout the shift. In reality, there might be short breaks or interruptions that could slightly affect the total number of drinks made.
