Answer:
v = 3.75 mph
Step-by-step explanation:
Constant speed motion
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:
[tex]\displaystyle v=\frac{d}{t}[/tex]
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:
[tex]\displaystyle v=\frac{0.75\ mi}{0.2 \ h}[/tex]
v = 3.75 mph
