Answer:
Width of the model is:
17.5 in
Step-by-step explanation:
The length of the classroom is 2.4 times its width.
Length=2.4×width
The length of the student's model is 42 in.
Let w be the width of student's model.
By using the equation Length=2.4×width , we get
42=2.4×w
⇒
⇒ w=17.5
Hence, width of the model is:
17.5 in

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.

After resting she still continued her journey to school.
This part also has a positive slope.
