Purchasing the Correctly Sized BMX Bike Based on Rider's Height

How is the size of a BMX bike frame determined based on the rider's height?

1. How does the equation b=0.29h+1.35 determine the size of the BMX bike frame?

Answer

Your best answer is A.

When purchasing a BMX bike, it is important to consider the size of the bike frame in relation to the rider's height. The equation b=0.29h+1.35 is used to determine the appropriate size of the BMX bike frame based on the rider's height in inches.

According to the equation:

1. As a rider increases one inch in height, the bike frame increases 0.29 inches. This means that for every inch increase in the rider's height, the bike frame size will increase by 0.29 inches.

2. The height of the rider gets multiplied by 0.29. This multiplication factor of 0.29 ensures that the bike frame size is proportionate to the rider's height.

3. The bike frame increases 0.29 inches for every 1.35 inches of the rider's height. This relationship between the rider's height and the increase in bike frame size is consistent and helps in determining the correct fit.

4. As a rider's height increases 1.35 inches, the bike frame increases one inch. This shows a direct correlation between the increase in the rider's height and the corresponding increase in the bike frame size.

By using the equation b=0.29h+1.35, a salesman can accurately calculate the size of the BMX bike frame that will best fit a customer based on their height. It is crucial to ensure a proper fit for a comfortable and safe riding experience.
