Answer:
y=1/2x+1/2
Step-by-step explanation:
In order to find the slope, you can use rise/run, in this case, the slope is 1/2 and the y-intercept is at (0, 0.5)
The main formula used in work-rate, distance-speed problems is:
Work=Rate*Time, or Distance=Speed*Time.
Thus, the time is:

.
In our problem, the total distance is 3 km + 3 km = 6 km.
the total time is 20 min + 25 min = 45 min.
60 minutes are 1 hour, then
45 minutes are

Thus, the average speed is : distance/time = 6 km/ 0.75 h = 8 km/h
Answer: 8 km/h
$8.50 because if he worked 40 hours a week you would multiple that by 52 because there are 52 weeks in a year. From there you would take the total he made and divide it by the hours he worked.
