    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?

    actually, 33 km = 108267.717 ft

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

    does this help?

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

    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

    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
