Calculate average speed
 

What is the corecct / simple formular to calculate the average speed?
In one colum I enter the distance (miles) traveled.
The other colum I enter the time. Time format is "hh:mm"

What I would like is to have the third colum look at both of these columns
and based on a formular?? display the average speed.

I have attempted this by trying the "CONVERT" function to convert the time
entered to all minutes but for some reason it does not work correctly??

For example the time entered is 3:05 which is 185 minutes.
When I use the "CONVERT" function it comes out as 183 ???
Is the problem with the time format that I'm using?

Try this...assume A1~C1 are Mile, Time, and Speed respectively. Make
sure time is input in text format so the formula bar displays "3:05"
not "3:05:00 AM".

C2 =
A2/(CONVERT(LEFT(B2,FIND(":",B2)-1),"hr","mn")+RIGHT(B2,LEN(B2)-FIND(":",B2)))

Format time cell as [h]:mm:ss
Avg Speed is distance over time, so
If A1 is time, and B1 is distance, C1 is
=B1/(A1*24)

And converting Hours to Minutes is
=A1*1440
