Question

What is the difference between the number of minutes in an hour and a half and the number of seconds in a minute and a half??

Answer 1

If you mean by one and a half hour and one and a half minute.............. Then in 1 & 1/2 hr , there are 90 min. that means 90*60 seconds = 5400 seconds....... whereas in 1 & 1/2 min., there are 60+30 sec = 90 sec. ....... So there is a great difference of seconds.
