Answer:
<em>v = 3.75 mph</em>
Step-by-step explanation:
<u>Constant speed motion
</u>
An object travels at a constant speed if the ratio of the distance traveled by the time taken is constant.
Expressed in a simple equation, we have:

Where
v = Speed of the object
d = Distance traveled
t = Time taken to travel d.
Sam walks from home to school for a distance of d=0.75 miles in t=12 minutes. To calculate the speed, we need to convert the time to hours.
t=12/60 = 0.2 hours. Now compute the speed:

v = 3.75 mph
The answers are X=-4 and Y=3.
The answer would be 6 because Ariadne shadow is 12 and Dixon shadow is 18 but it says if Ariadne shadow is 5 Dixon would be 6 divide be 3 .
