Guven that the <span>distance
d that a certain particle moves may be calculated from the expression 
where a and b are constants; and t is the elapsed time.
Distance is a length and hence the dimension of distance is L.
Now,

Answer:
ft
Step-by-step explanation:
We know that the height of the object and the height of the shadow it casts are proportional. Therefore, if we let the length of the tree be , we can set up the following proportion to solve for it:
Solving for , we get:
(Cross-Products Property)
(Simplify)
(Divide both sides of the equation by 8 to get rid of
's coefficient)
(Simplify)
Therefore, the tree is ft tall. Hope this helps!
