Question

How many minutes are there in x hours, y minutes and z seconds.

Sum

Solution

We know that 1 hour = 60 minutes
1 minutes = 60 seconds
Number of minutes in x hours = 60x
Number of minutes in y minutes = y

Number of minutes in z seconds = `"z"/(60)`

Total minutes = 60x + y + `"z"/(60)`.
