Answer:

5670 seconds = 1.575 hours

Step-by-step explanation:

Given : 60 seconds = 1 minute

            60 minutes = 1 hour

To Find : 5670 seconds =  ? hours

Solution :

Since we are given that    

60 minutes = 1 hour


so, \(1 min =\frac{1}{60} hour\)    (a)


and we are also given 60 seconds = 1 minute

So, using (a)


\(60 seconds =\frac{1}{60} hours\)


⇒ \(1 second = \frac{1}{60\times 60} hours\)


⇒\(5670 seconds = \frac{1}{60\times 60}\times 5670 hours\)


⇒\(5670 seconds = 1.575 hours\)


Thus , 5670 seconds = 1.575 hours
