First 32 miles at an average speed of 64mph.
So the time for these 32 miles is:
Rest of the trip:
200 - 32 = 168 miles in 4 - 0.5 = 3.5 hours. So the average speed is of:

Answer:
There is a direct relationship between the amount of money that Jacob earns and the number of hours he works.
Step-by-step explanation:
In math, a direct relationship exists when a change in one variable causes another variable to change in the same manner. E.g. if variable X increases, then variable Y will increase. If variable X decreases, then variable Y will decrease.
In this case, if Jacob works 25 hours per week, he will earn $243.75. If he works 30 hours, he will earn $292.50. But if he only works 20 hours, he will earn $195.
