Thread: convert units

its just metric problems.

a car can travel 33km/gal of gas if gas selss .99/liter. how many feet can the car travel on
8.45 worth of gas.

from 33km/1gal. i got it to 99000ft/1gal.

from .99/1 liter... i converted it to 3.96/ 1 gal [hopefully i did it right.

but how does 8.45 play in the problem?

haha, good! because i was going to tell you to take some Gas-X or Beano

actually, 33 km = 108267.717 ft

does this help?

$8.45 buys 8.45/0.99 = 8.5354 litres of gas. how far could you drive with that?

i hear beano is better)

but... well i converted 33km/1gal to meters/km [cancelling km] the ft/1m....
what did i do wrong?

your conversion factor is probably wrong. remember, 1 km = 3280.8399 ft

its the US. i guess we are the only that are not using the metric.

so my chemistry teacher informed us to convert a unit at a time. in this problem, from kilometers to meters to feet.

ok, you probably lost a few decimal places throughout the double conversion and it set things off. well, now you have the conversion

wait...how many feet are in a meter? is there a way that i can derive it... so to say

you can't really derive the conversion factors per say, they are what they are for basic units. 1 meter = 3.2808399 ft

you could derive this by the first conversion factor though

oh!

i messed up in the meters...

i keep messing up... and i have a test on conversions wednesday...

thank you Jhevon...

ok.

so i hope that you can finish the problem now. i am leaving soon, so i guess someone else would have to help you if you get stuck again
