Answer 2

Answer:

The reaction take 2.05 hours.

Step-by-step 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

$1 \text{seconds}= 60\times 60 \text{hours}$

$1 \text{seconds}= \frac{1}{60\times 60} \text{hours}$

$7380 \text{seconds}= \frac{7380}{60\times 60} \text{hours}$

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

Nearest to hundredth the reaction take 2.05 hours.
