Expressing time

[Tesnobay]

Hi,
What is the best way to express time traveled when you will the multiply by a monetary rate to get compensated?
For example, should 1 Hour and 30 minutes of travel be 1.5 or 1:30? Time will only be in 15 minute intervals: 1.25, 1.5, 1.75 etc
It will then me multiplied by reimbursement rate say $.50. Total amounts will then be summarized on a separate sheet.

I want to use 1.5 since it seems to make more sense, but it is nagging at me.

Thanks

Hello Tesnobay,

Convert the minutes to decimal. One minute = 1/60 of an hour or .01666667.

Travel time in minutes * .01666667 * rate
90 * .01666667 * .50 = .749997
