Answer:

The last graph best represents the story

Step-by-step explanation:

Mary left for school from rest. So the initial speed is zero.

So we start from the origin and draw a straight line with a positive slope to running, that is as time increases , distance covered also increases.

When she is resting, her speed is zero so we draw a horizontal line to indicate this second phase of her journey.

After resting she still continued her journey to school.

This part also has a positive slope.

JulijaS [17]

Answer:

steps below

Step-by-step explanation:

arc QR = 2x57 - 41 = 73

arc PQ = 360 - 73 - 41 - 137 = 109

m∠Q = (41+137) / 2 = 89°

m∠R = (109+137) / 2 = 123°

m∠S = (109+73) / 2 = 91°

check: ∠R+∠p = 123+57 = 180

           ∠Q+∠S = 89+91 = 180
