Given the following information, we want to represent the 4 expression shown in practical terms:
a)
s + t
First truck makes "s" trips
Second truck makes "t" trips
So, "s+t" means
the total number of trips made by the two trucks
b)
x + y
the volume transported by 1st truck = x
the volume transported by 2nd truck = y
So, "x+y" is
total amount, in cubic yards, transported by the two trucks per trip
c)
xs + yt
xs is total number of cubic yards in s trips (total) >> 1st truck
yt is total number of cubic yards in total t trips (total) >> 2nd truck
Hence,
"xs + yt" means
total number of cubic yards transported by two trucks in all trips
d)
[tex]\frac{xs+yt}{s+t}[/tex]
This is the total in all trips by two trucks divided by "s+t", which is total number of trips by two trucks
We can say this expression tells us:
total number of cubic yards transported by two trucks PER trip
