4) Castel left the airport and drove toward his cabin on the lake at an average speed of
50 mph. Ashley left at the same time and
drove in the opposite direction with an
average speed of 60 mph. Find the
number of hours Ashley needs to drive
before they are 330 mi. apart.

Step-by-step explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :  

                    x-10-(44)=0  

Step by step solution :

Step  1  :

Solving a Single Variable Equation :

1.1      Solve  :    x-54 = 0  

Add  54  to both sides of the equation :  

                     x = 54  

One solution was found :

 x = 54
