If an ant walks at a rate of 0.0001 M/S, how many minutes should it take it to walk down Jane's finger-distance of 7.6 cm.

The answer is 2.6--->

but im lost in what to convert first...

see post #2 here for two methods of how to convert units

(by the way, 1 m = 100 cm) - Sep 9th 2008, 05:46 PM>_<SHY_GUY>_<

*Sorry for the double post*

i keep getting 4.56 as the answer...but before multiplying it from 7.6....i get .6...

i know i am doing something wrong - Sep 9th 2008, 06:36 PMAryth
Well, you can use 1 number at a time until you can move to the next one. We start with:

$\displaystyle 0.0001 \frac{m}{s}$

Now, we know that:

1 m = 100 cm, so:

$\displaystyle 100\frac{cm}{m}*(0.0001)\frac{m}{s}$

$\displaystyle = 0.01\frac{cm}{s}$

Now, we also know that:

60 s = 1 min, so:

$\displaystyle 60\frac{s}{min}*0.01\frac{cm}{s}$

$\displaystyle = .6 \frac{cm}{min}$

So, what you have to do is divide that answer into the total distance:

$\displaystyle \frac{7.6 \ cm}{.6\frac{cm}{min}}$

$\displaystyle = 7.6 \ cm*\frac{1}{.6}\frac{min}{cm}$

$\displaystyle = 12.6 \ min$

So, I got a completely different answer than you... But I'm pretty sure I didn't do anything wrong.
