No, earth cannot have 30 seconds in a minute. Unless it started rotating at twice the speed (making a day half as long).
No. 30 seconds is always half a minute. However, on other planets, since they rotate at different speeds, time is counted differently to how it would be on Earth. (If one rotation on the planet's axis is "a day", but they rotate quicker than the Earth does, a minute will be fewer seconds that it would be on Earth). You may find a planet where 30 seconds = a minute, however I don't know which one that could be off hand.
30 seconds in half a minute (there are 60 seconds in a minute)
1 minute and 30 seconds is 1.5 minutes.
30 seconds is 50% of a minute.
It is 30/60 or 1/2 simplified
30 seconds is half a minute (0.5 minutes), as there are 60 seconds in a full minute.
30 seconds
love this pic
1 minute and 30 seconds
a minute and 30 seconds
30 seconds are one half minute. 60 seconds are one minute.
so you are charged a minute for every minute you use? or 30 seconds if it is only 30 seconds....
