The equivalent rate to 9 miles in 45 minutes is C. 13.5 miles in 67.5 minutes
<h3>How to calculate the value?</h3>
From the information, Billie bikes 9 miles in 45 minutes. It should be noted that this is:
9/45 = 1/5
Therefore, the equivalent option is:
13.5 miles in 67.5 minutes. It should be noted that when it's divided, it'll be 1/5
Therefore, the correct option is C

Step-by-step explanation:
5÷7 = 0.7142857142857
The measure of the angle ∠ABD is 64 degrees
<h3>How to determine the measure of the angle?</h3>
From the question, we have the following parameters:
Ray BA bisects ∠CBD
∠CBD = 5x + 18
∠ABC = 3x - 2
Because of the bisection, we have
∠ABC = ∠ABD
∠ABC * 2 = ∠CBD
Substitute the known values in the above equation, so, we have the following representation
(3x - 2) * 2 = 5x + 18
Open the brackets
6x - 4 = 5x + 18
Evaluate the like terms
x = 2
Recall that
∠ABC = ∠ABD
So, we have
∠ABD = 3x - 2
This gives
∠ABD = 3 x 22 - 2
Evaluate
∠ABD = 64
Hence, the angle is 64 degrees
