Answer:
15.71 ft
Step-by-step explanation:
Given that:
width of the circular track = 2.5ft
Suppose the radius of the inner circle is 57 ft since it is not given
Then the radius of the outer circle = (2.5 + 57) ft = 59.5 ft
The circumference of a circle = 2πr
For inner circle now, the circumference = 2 × π × 57 ft
For inner circle now, the circumference = 358.14 ft
For the outer circle, the circumference = 2 × π × 59.5 ft
For the outer circle, the circumference = 373.85 ft
The difference between the circumference of the outer wheel from the inner wheel shows how farther does a wheel on the outer rail travel than a wheel on the inner rail of the track in one turn
∴
= ( 373.85 - 358.14 ) ft
= 15.71 ft
The equation which is equivalent to the equation as given in the task content is; 6x -8y = 36.
<h3>Which equation is equivalent to the equation as given in the task content?</h3>
According to the task content, it follows that the equation which is given in the task content is;
3x -4y = 18.
Hence, upon multiplication of the whole equation by 2; the resulting equation from the multiplication is;
6x -8y = 36
Ultimately, the equivalent equation is; 6x -8y = 36.
