Step-by-step explanation:
Given
--- driver 1
-- driver 2

Required
The time they passed each other
First, we determine the function of driver 2.
We have that:
and 
So, the function is:


The time they drive pass each other is calculated as:


Collect like terms


Divide through by 2t

Step-by-step explanation:
<u>System of Equations</u>
Let's call:
x = number of nickels in the student's pocket
y = number of dimes in the student's pocket
Each nickel has a value of $0.05, so x nickels have a value of 0.05x
Each dime has a value of $0.10, so y dimes have a value of 0.10y
The student has a total of 10 coins, thus:

The total value of the coins is $0.85, thus

The system of linear equations that represents this scenario is:

Think it of a fraction problem,
