The average track laid by the Union Pacific Company per month is 15.1 miles track per month.
<em>"Your question is not complete, it seems to be missing the following information";</em>
the two companies met at Utah, approximately 6 years after the construction began.
The given parameters;
- the average track laid by Central Pacific Company = 9.6 miles track per month
- the total track laid by the two companies, t = 1775 miles track
- duration of the construction = 6 years
<em>let the average track laid by the Union Pacific Company per month</em> = y
The average track laid by the Union Pacific Company per month is calculated as follows;
(12 x 6 )9.6 + (12 x 6)y = 1775
691.2 + 72y = 1775
72y = 1775 - 691.2
72y = 1083.8
Thus, the average track laid by the Union Pacific Company per month is 15.1 miles track per month.
