B. 10hrs - 6hrs = 4hours
C. BC is deacceleration = -dv/dt
CD is constant acceleration = dt = 0
2 steering wheels manufactured each hour were defected
There were 50 steering wheels manufactured per hour
The fraction is
Divide 2, which is the numerator by 50, which is the denominator
2÷50=.04
To change any decimal into a fraction, multiply by 100
The multiply .04 by 100 to change into a percentage
.04×100=4.⇒4%
4% is the percentage of defective steering wheels
