A sensor checks the temperature every hour for a total of 10 hours.
If the temperature is above $25^\circ\text{C}$, it records a 'High'. If it's $25^\circ\text{C}$ or below, it records a 'Normal'. If 6 readings were 'High' during the 10 hours, how many readings were 'Normal'?
If each 'High' reading triggers an alarm that sounds for 2 seconds, and 'Normal' readings do not trigger any alarm, what was the total duration the alarm sounded over the 10 hours?
