Given
d(t) = 0.8t ^2
t= 5 secs
d(5) = 0.8(5)^2 = 0.8 * 25 = 20
t= 10 secs
d(10) = 0.8(10)^2 = 0.8 * 100 = 80
20 m / 5 secs = 4 meters per sec
80 m / 10 sec = 8 meters per sec
4 mps + 8 mps = 12 mps
12 mps / 2 = 6 mps
6 mps is the average speed of the rock between 5 and 10 sec after being dropped
René Descartes provided the first systematic link between Euclidean geometry and algebra.
<h3>What is Geometry?</h3>
This branch of mathematics involves the study of object shape, their spatial relationship and that of their surrounding space.
René Descartes is referred to as the father of analytic geometry due to him establishing the relationship between Euclidean geometry and algebra.

5 is b because 3/6 is equivalent to 1/2
6 is a because 1/6 is less than half
Let
x = scale
For this case you should count how many divisions there are in the longest dimension.
14
Then, as the longest dimendion of the park is 63 meters then, the scale is
14x = 63
x = 63/14
x = 4.5
answer
the scale is 4.5m
