A monitoring system records data every 45 minutes. If it runs continuously for 3 days, how many readings will be recorded?
96
The system runs continuously for 3 days, which is \(3 \times 24 \times 60 = 4320\) minutes.
Since a reading is recorded every 45 minutes, the number of readings equals \(\frac{4320}{45} = 96\).
Hence, 96 readings will be recorded.
