Question, I did a problem and got .02 hrs.  I'm confused about how to convert it to minutes.  Can someone help?

calculusxy · Answer

You might want to convert it with a proportion:
$$\frac{ hour }{ minutes } = \frac{ hour }{ minutes }$$
Replace them now:
$$\frac{ 1 hour }{ 60 minutes } = \frac{ 0.2 hour }{ x }$$

calculusxy · Answer

Solve for x now.

One minute and twenty seconds?

anonymous · Answer

yeah, I got the 1.2, so I assume the .2 would be the units of seconds which would make it twenty seconds

calculusxy · Answer

Wait isn't it:
60 x 0.2 = 12 ?

calculusxy · Answer

You got that now?

anonymous · Answer

Ooh, you're right.  Good catch.  So it would be 1 minute 12 seconds.  Thanks so much!  You've been a great help.

calculusxy · Answer

No. Just 12 minutes.

calculusxy · Answer

There isn't any decimals, so just keep it simple with that.

calculusxy · Answer

Understand?

anonymous · Answer

The original was .02 not .2.  60 * .02 = 1.2.
The 1 would be a minute.
Then 60 * .2 (the .2 at the end of the 1.2) would be 12 seconds.  
Wouldn't that be right?

Yeah, sorry I was mixed up, you're right!

haha no worries!  Thanks for your help!
