Answer 1

Radius of the tire,

Circumference of the tire, $C = 2\pi r = 2\pi (0.230 m) = 1.445\ m$

Total distance travelled before wearing of the tire = 60000 km

Number of revolutions each tire makes is ,

$N =\frac { Distance \ travelled \ by \ the \ tire }{circumference \ of \ the \ tire}$

N = 60000 x 10m 1.445 m

$\boxed {N =4.152\times 10^7}$

Therefore, the number of revolutions that each tire makes before wearing out are 4.152 × 107 .
