Answer:
4 units.
Step-by-step explanation:
Let's use a ratio
72 : 360
8 : 40
1 : 5
The arc is 
of the total circumference.
The arc length is 4
The measure of m<CBD is 63 degrees
<h3>Circle Geometry</h3>
According to line geometry, the sum of angles on a straight line is expressed as:
arcCD + m<CBF = 180
Given that
arcCD= 5x + 3 and;
m<CBF = 11x - 15
Substitute
5x + 3 + 11x - 15 = 180
16x - 12 = 180
16x = 192
x = 12
Determine the measure of m<CBD
m<CBD = arc CD = 5x + 3
m<CBD = 5(12) + 3
m<CBD = 63 degrees
Hence the measure of m<CBD is 63 degrees

180/60=3
42/3 is 14
so 14 km per hour is your answer
$2.00x15%=0.3
$2.00+0.3=$2.30
Hope this helps
