90 hours
There are 1.5*60*60 = 5400 seconds
There are 60 seconds in 1 minute, therefore 60x90 = 5400 seconds in 90 minutes.
There are 5400 seconds in 90 minutes which is greater than 540 seconds
60 min = 1 hr ⇒ 5400 min = 5400 ÷ 60 hr = 90 hr
There are 60 seconds in one minute. Therefore, 5400 seconds is equal to 5400/60 = 90 minutes.
There are 60 seconds in one minute. Therefore, 5400 seconds is equal to 5400 / 60 = 90 minutes.
5400
60 seconds an 1 minute 60 minutes in 1 hour 30 minutes in half an hour 90 minutes in one and a half hours. So 90 minutes * 60 seconds = 5400 seconds
90 hours
3,600 seconds = 1 hour 5,400 seconds = 11/2 hours
There are 1.5*60*60 = 5400 seconds
There are 60 seconds in 1 minute, therefore 60x90 = 5400 seconds in 90 minutes.
1 hour = 3600 seconds 30 minutes = 1800 seconds 1 hour + 30 minutes = 5400 seconds
There are 5400 seconds in 90 minutes which is greater than 540 seconds
60 min = 1 hr ⇒ 5400 min = 5400 ÷ 60 hr = 90 hr
5400 seconds. ************************ 60 seconds = 1 minute 60 minutes = 1 hour so 1 and a half hours is 1.5x60x60= 5400 BUT I read question as 1 hour (60x60=3600seconds) plus half minute (0.5x60 = 30 seconds) so total is 3660 seconds
