Answer:
12
Step-by-step explanation:
The formula for distance between points is 
So when you inserts the coordinates in this formula, it would be 



=12.08305
Usually, distance is round to whole number. So, it would be 12
11,000 - rounded to the nearest thousand!
In this problem there might be a number that you need to add before the "( x 3)" then your answer will be 20 = 32 - 12 = 20
Multiply each hourly rate by x ( time to complete the work) add it to the service call for each and then set the equations equal:
50 + 40x = 30 +45x
Subtract 30 from both sides:
20 + 40x = 45x
Subtract 40x from both sides:
20 = 5x
Divide both sides by 5
x = 4
The length is 4 hours.
