This question already has an answer here:
I have a text-string 1 hour 43 mins
How can I convert this to output 1.75 using PHP?
(and this be true for all other possibilities, rounding to nearest .25 hours)

You take the hours, store it in a variable called hours. Take the minutes, device them by 60, and do a simple addition.
Take care of the case where minutes = 0, because it will throw an exception since you cannot divide by 0
