Question

1.
The diameter of the rear wheel of a cart is 1.5 m. In travelling a certain distance the rear
wheel makes 80 revolutions while the front wheel makes 240 revolutions. Find the diameter
of the front wheel.
​

Answer 1

Step-by-step explanation:

settings the equation

2πR★80=2πr★240

or, r =(80/240)★(15/20)=.25

Therefore diameter front wheel=2r=.50m

where is (r) radius of the front wheel and (R) is radius of the rear wheel.
