a car travels from point s at (-5,7) to point t at (-5,-1). if each unit represents 20 miles, how long will it take the car to travel this distance, traveling at 40 miles per hour?

The value is  

Step-by-step explanation:

From the question we are told that

  The initial  position of the car is  

   The final position of the car is    

    The speed of the car is

Generally the distance covered by the car along the x-axis is  

=>    

Generally the distance covered along the y-axis is  

=>

=>  

Generally the resultant distance covered is  

=>  

=>  

From the question we are told that 1 unit of the distance covered is  20 miles so  

    8 units is

=>        

Generally the time taken is mathematically represented as

=>    

=>
