1 1/2 hours to seconds?

Question

convert the answer, please .

Answer 1

1 1/2 hours is the same as 1 hour and 30 mins.

In 1 hour there is 60 mins, so all together in 1 1/2 hours there are

60 + 30 mins = 90 mins

And since in 1 min there is 60 secs

So 90 mins = 90 x 60 secs = 5400 secs

So in 1 1/2 hours there are 5400 secs
