Respuesta :

1 hour equals 60 minutes.

Divide the minutes by 60 to find the decimal portion of the time:


21 minutes / 60 = 0.35

Now add that to 3 hours to get decimal hours:

3 hours 21 minutes as a decimal would be 3.35 hours


So we know that 1 hour is 1.0,

And we have 3 hours, so 3.0,

And 1 hour is 60 minutes,

So we take 21/60,

And we get 0.35,

So the correct answer is 3.35

Hope This Helps
