How many days is 3500 minutes?

Answer 1

Use unit analysis to solve this problem.

In one hour there are 60 minutes and in one day there are 24 hours.

That is, hr/60min and day/24hr

(The division can be pronounced "per", as in "60 minutes per hour" or "one hour per 60 minutes")

Using these two terms, divide out the minutes and multiply in the days:

3500min * hr/60min * day/24hr

The "min" units in the numerator of 35000 cancels out with the 60 min in the denominator of hr/60min. Same with the "hr".

What you are left with is 3500 * 1/60 * 1day/24

Multiplying this out is approximately 2.43 with the unit of "days" left in the numerator.
