Final Answer:
Converting minutes to seconds increases the numerical value by a factor of 60, resulting in more units for the same duration. Thus, the correct answer is option 3) There would be more units.
Step-by-step explanation:
When Scotty measures the time in seconds instead of minutes, the number of units will increase. Since there are 60 seconds in a minute, the conversion from minutes to seconds multiplies the original value by 60. In this case, when Scotty made a sandwich in 3 minutes, converting it to seconds would be 3 minutes * 60 seconds/minute = 180 seconds. So, the number of units increases from 3 to 180, resulting in more units when measured in seconds.
When we convert time units, we are essentially subdividing each minute into 60 parts (seconds). So, the total count of units increases. In this scenario, the seconds provide a finer granularity of measurement compared to minutes, leading to a higher numerical value for the same duration. Therefore, choosing seconds over minutes increases the number of units used to measure the time it takes for Scotty to make a sandwich.
Thus, the correct answer is option 3) There would be more units.
