Answer:
The constant of proportionality is 1.5 and the value of q is 9.
Step-by-step explanation:
Assume Hours as 'x' and Miles walked = 'y'
Constant of proportionality means the same value of 
is maintained throughout.
So, note that 
= 1.5
This means that 
should also equal 1.5.
= 9.
Therefore, the value of 'q' is 9.
Option D:
Right triangle
Solution:
Let us first define obtuse, acute right triangle and supplementary.
<u>Obtuse angled triangle:</u>
If any one of the angle in the triangle is more than 90°, then the triangle is an obtuse angled triangle.
<u>Acute angled triangle:</u>
If all the angles of the triangle are less than 90°, then the triangle is an acute angled triangle.
<u>Right angled triangle:</u>
If any one of the angle in the triangle is exactly 90°, then the triangle is a right angled triangle.
<u>Supplementary:</u>
If sum of the angles is 180°, then the angles are supplementary angles.
But this is not a kind of triangle.
In given triangle one of the angle is 90°.
Therefore, this is a kind of right triangle.
Option D is the correct answer.
The answer is 3/10 since percentages are out of 100
