Your factory installed tires have a comfort that 95 inches if the odometer reading reading is 32,000 miles on your car you have

Sloan [31]

Answer:

The correct solution is "35440.8".

Step-by-step explanation:

The given values are:

Bigger tire's circumference,

= 103 inches

Factor installed tire's circumference,

= 95 inches

Odometer reading,

= 32,000 miles

As we know,

⇒ $Actual \ distance = K\times odometer \ reading$

Where,

⇒ $K = \frac{Bigger \ tier \ circumference}{Factor \ installed \ tier \ circumference}$

i.e.,

⇒ $K=\frac{103}{95}$

On applying the formula,

⇒ $Actual \ distance \ travelled=\frac{103}{93}\times 32,000$

⇒ $=35440.8$
