A chemical reaction took 7380 seconds. How many hours did the reaction

take? If necessary, round your answer to the nearest hundredth of an hour.

Answer: 2.05 hours

Step-by-step explanation: There are 60 seconds in a minute, and 60 minutes in an hour. To find the seconds in an hour, multiply 60 by 60.

60 x 60 = 3600

There are 3600 seconds in an hour. Divide 7380 by 3600 to find the number of hours.

7380/3600 = 2.05

The reaction took 2.05 hours.
