Answer:
Dividing by a fraction is multiplying by the reciprocal
15.09/1/100=15.09*100=1509
267.4/1/10=267.4*10=2674
Distance = rate*time, or
distance = (average speed)* time, so
average speed = distance/ time.
average speed = 205 mi / (3/12) h = 205 mi/ (1/4)h = 205*4 mi/h=
= 820 mi/h
It is looks to high for speed of the truck,
probably time should be 3.12 h,
then
average speed = 205 mi / (3.12) h ≈ 65.71 mi/h.
That looks close to real life.
Using the midpoint concept, it is found that the value of a is of a = 2.
<h3>What are the coordinates of the points?</h3>
Researching this problem on a search engine, the coordinates are given as follows:
<h3>What is the midpoint concept?</h3>
The midpoint between two points is the halfway point between them, and is found using the mean of the coordinates.
Hence the following system of equations can be built:
(b + 1 + 2a)/2 = 3.
b + 1 + 2a = 6.
b = 5 - 2a.
(a + 2 + 3b + 3)/2 = 5
a + 3b + 5 = 10
a + 3b = 5.
Since b = 5 - 2a, we have that:
a + 15 - 6a = 5.
5a = 10
a = 10/5
a = 2.
The value of a is of a = 2.
