You were allowed to use your phones for exp 3 (DRL) to keep track of<br>
the elapsed time. You can do so again for exp 4 (VRT). However,
I've<br>
seen a couple of things you shouldn't do.<br>
<br>
1) Your stopwatch will likely have times such as 3:22:44.3.<br>
This is hours:min:sec.fractions of a second. There's no<br>
point in recording the fraction of a second. You could not<br>
be this accurate for either exp 3 or 4.<br>
<br>
2) You can not leave your time in this format for either exp 3 or
4.<br>
You will need to convert it to either all seconds or minutes,
it really<br>
doesn't matter which you choose. Turns out there is a pretty
easy<br>
way to do this. Go to the following link and follow the
directions:<br>

<br>
Put your time in as 0:00:00 (h:mm:ss). If your time is 30 min
and 30 sec<br>
enter it as 0:30:30. If it's 1 hour, 5 min and 5 sec enter it
as 1:05:05.<br>
This appears to work fine and gives time in minutes. You can
leave it<br>
in minutes. If you want seconds just multiply the equation
shown by 60.<br>
