Final answer:
The expression '60 minutes/1 hr x 24 hr/day x 365 days/year' calculates the number of minutes in a year. When the multiplications are performed, we get an answer in minutes, which would be 525,600 minutes.
Step-by-step explanation:
The question relates to unit conversion within time measurements. Specifically, the equation 60 minutes/1 hr x 24 hr/day x 365 days/year is used to calculate the number of minutes in a year. Performing the multiplications (60 x 24 x 365), we see that the resultant number does indeed give us the number of minutes because as the conversion factors are applied, the units of hours and days cancel out, leaving us solely with minutes. Therefore, the answer to the question, which is 525,600, is expressed in minutes.
