    I'm not a nurse but I am a math teacher and you simply have to set this up as a proportion. After you solve the proportion you have to convert .44 to minutes which is approximately 27. Here's the proportion:

    500/n = 145/1
    145n = 500
    n = 3.45
    n = 3 hours and 27 minutes.

    I hope this helps.
