Answer:
Every 30 hours
Step-by-step explanation:
Train A arrives at central station on the hour and every 12 minutes, you mean with that on every 72 minutes
Train B arrives at central station on the hour and every 15 minutes, you mean with that on every 75 minutes
In accordance with the given, the smallest number containing numbers 72 and 75 is 1800 minutes.
When we convert this number of minutes in hours we get:
1800 / 60 = 30 hours

and 
Step-by-step explanation:
Given:

Solving for the positive part of the equation:

Solving for the negative part of the equation:

<em><u>The polynomial that represents the difference between the cost of distributing by train and the cost of distributing by truck is:</u></em>

<em><u>Solution:</u></em>
<em><u>The cost of distributing by train can be modeled as:</u></em>

<em><u>The cost of distributing by truck can be modeled as:</u></em>

where x is the number of tons of product distributed
To find: Difference between the cost of distributing by train and the cost of distributing by truck
Difference = cost of distributing by train - cost of distributing by truck
Let f(x) = difference in cost between trains & trucks



Thus polynomial that represents the difference between the cost of distributing by train and the cost of distributing by truck is found
