Josh has a device that automatically records the temperature in his lab every 5 seconds. To perform an analysis of environmental conditions, Josh lets the device record data for one hour. How many instances of data will the device record? Think carefully first, then make a decision:
There are 60 minutes in an hour, and 60 seconds in a minute so there are 60 * 60 = 3600 seconds in an hour. The device records data every 5 seconds so there will be 3600 / 5 = 720 instances of data in an hour. So, the answer is 720.
