See a solution process below:

Explanation:

Let's call the number of hours we are looking for: hh

And, let's call the number of mins: mm

Because there are 60 minutes in an hour we can write the equation for hh as:

h = m/60h=m60

So, if you had color(red)(60)60 minutes you could substitute this for color(red)(m)m and solve for hh giving:

h = color(red)(60)/60h=6060

h = 1h=1

m/60 hours in m minutes

Explanation:

We know there are 60 min in 1 hour ... 60 min= 1 hr
So there are 60h min in h hours .... 60h min = h hours
So there are 60h minutes in h hours.
Now, to reverse this to get hours in m minutes
Start again with
60 min = 1 hr
60m min = m hr
m min = m/60 hr
So there are m/60 hours in m minutes

Check
If m=60 minutes
60 min = 60/60 hr = 1 hr
Checks ok
