Final answer:
To find x in an equation with r, we can use the equation x = r0 and rearrange the equation to solve for x. Once we have x, we can determine the distance traveled using the relationship between x and 0.
Step-by-step explanation:
To find x in an equation with r, we can use the equation x = r0, where r is the radius of the wheels and 0 is the number of revolutions in radians. Before using this equation, we need to convert the number of revolutions into radians.
The equation x = r0 is best because it includes only one unknown, x. We can rearrange this equation to solve for x. Once we have the value of x, we can determine the distance traveled using the relationship between x and 0.
For example, if we have a radius r of 0.15m and 0 of 75.4rad, we can substitute these values into the equation x = r0 to find x = (0.15m)(75.4rad) = 11m.
