At the start of a trip, the odometer on a car reads 20809 miles. At the end of the trip, 14.5 hours later, the odometer reads 21353 miles. What is the average speed the car traveled during this trip?miles/hour

37.5 miles per hour

Step-by-step explanation:

To get the average speed, we need to know the number of miles traveled and for how many hours did the car traveled.

We already know the number of hours traveled and this is 14.5 hours. To get the distance traveled, we need to subtract the initial odometer reading from the final odometer reading. This is 21,353 miles - 20,809 miles = 544 miles

The average speed is thus distance/time = 544/14.5 = 37.52 approximately 38 miles per hour

Compute the equations of the lines using point-slope form:

Line l:    

✔ y - 4 = 0.5(x - 1)

Line m:  

✔ y - 5 = -0.75(x - 43)

Finally, simplify to slope-intercept form:

Line l:    

✔ y = 0.5x + 3.5

Line m:  

✔ y = -0.75x + 37.25
