How many seconds are in 2 hours? Conversion factors: 60 seconds = 1 minute, and 60 minutes = 1 hour. Show all work using dimensional analysis

Answer 1

To convert 2 hours to seconds using dimensional analysis, we can set up a proportion:

2 hours * (60 minutes / 1 hour) * (60 seconds / 1 minute) = 2 * 60 * 60 seconds

Using the conversion factors, we can cancel out the units we don't need:

2 * 60 * 60 = 7200 seconds

Therefore, there are 7200 seconds in 2 hours.
