Firm Weight of wood delivered Distance covered
P 200 250
Q 500 800
The Van cost $675,000 to operate for the week. Each delivery was carried separately and there were no other deliveries during the week.
What is the cost per kilogram/ kilometre of wood delivered in the week (to the nearest $0.01)?
You have to calculate total kilogram-kilometres and divide total cost by that figure:
200 x 250 = 50,000
500 x 800=400,000
So in total: 50,000 + 400,000 = 450,000 kg-km
Therefore cost per kg-km = $675,000/450,000 = $1.5 per kg-km.
Hope this helps.
P.S. Note that although sometimes written like that, it's not kg/km (meaning kg divided by km), rather it's kg multiplied by km, that's why I prefer to write it with "-", not with "/".
May be :-
kg p q
1 : 2.5
q = 2.5 p
is it correct
Thanks Samir Alaskarov,
P.S. is awesome.
you mean cost per kilogram per kilometer is cost/(kg*km) ain't it?
Or say cost per kilometer per kilogram means the same.
The same mathematical expression can be written as
cost/(kg*km) = (Cost/kg)/km
Now try expressing (Cost/kg)/km into words....
