# Math Help - Conversions?

1. ## Conversions?

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.

but im lost in what to convert first...

it doesn't matter what you convert first. you can convert m --> cm and then s --> min or vice versa

so that would mean that i can go

0.0001 m x ...... wait.... but i would have to cancel one of the units first.
-----------
s

multiply it by 91.44 cm/ 1 m?

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

(by the way, 1 m = 100 cm)

Wow... How Did I Miss 1 m = 100cm Thanks

so in other words...Tackle one unit until it is on the one unit you want.... then tackle the next?

6. 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

7. Well, you can use 1 number at a time until you can move to the next one. We start with:

$0.0001 \frac{m}{s}$

Now, we know that:

1 m = 100 cm, so:

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

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

Now, we also know that:

60 s = 1 min, so:

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

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

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

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

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

$= 12.6 \ min$

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