Question 40903
2000 miles = x inches
126,720,000 inches
First car's tire:
{{{C = 2(pi)r}}}
{{{C = (pi)15}}} is about 47.12
126,720,000/47.12 = about 2,689,303 rotations
Second car's tire:
{{{C = 2(pi)r}}}
{{{C = (pi)16}}} is about 50.27
126,720,000/50.27 = about 2,520,787 rotations
The first car's tire rotates more, so there is probably more 'ware and tare'.
