90 dollars divided by 60 minutes= $1.5 per minute
To convert from dollars per hour to dollars per minute, divide the hourly rate by 60 (since there are 60 minutes in an hour). So, if 90 dollars are earned per hour, this would be equivalent to earning 1.5 dollars per minute (90 / 60 = 1.5).
90 seconds. One minute is 60 seconds, 0.5 of a minute (half) is 30 seconds. 60 + 30 = 90
Perhaps minute intervals might be better than minute intervals.
