its already round to the nearest hundredths of an hour

Answer 2

The reaction take 2.05 hours.

Explanation:

Given : A chemical reaction took 7380 seconds.

To find : How many hours did the reaction take?

Solution : We have to convert seconds into hours.

1 hour = 60 minutes

1 minute = 60 seconds

`1 \text{seconds}= 60* 60 \text{hours}`

`1 \text{seconds}= (1)/(60* 60) \text{hours}`

`7380 \text{seconds}= (7380)/(60* 60) \text{hours}`

`7380 \text{seconds}= 2.05 \text{hours}`

Nearest to hundredth the reaction take 2.05 hours.
