The unit rate depicted in the graph is must be
3 laps in 4 minutes . As we can see in the graph that the point meets at the 3 laps and 4 minutes so this option must be suitable for the above question.

h=20w
in one week hector works 20 hours
in two hector works 40 etc
h = hours and w = weeks. the money is just extra information.
h=20w works because if it has been two weeks we substitute the w with the number 2 and can solve
h=20(2)
h=20x2
h=40
This proves that the equation is true
