I agree the data are questionable
OR
the truck driver doesn't go as fast when he has 10000# of cows :)
Is there a baseline gas mileage with a nonlinear increase (arctangent) as the weight decreases? Gas mileages are notoriously non-linear for most variables.
I have quite an interesting problem that I cannot explain...Kathy Daniel <kcdohs@comcast.net> 5/7/2008 4:02 pm >>>
Our Ag teacher set up this scenario for me:
one 5000# truck gets about 18 miles per gallon
same 5000# truck pulling a 4000# trailer gets 8 miles per gallon
same 5000# truck pulling a 4000# trailer + 10000# of cows ALSO gets 8
miles per gallon.
Any ideas why the empty and the full trailer both get the same
mileage? This same pattern is also present in a different trailer and
truck combination.
thanks,
Kathy
