Answer 1

If the odometer reading is 30,000 miles on your car and you have changed the factory-installed tires(circumference of 93 inches) to bigger tires(circumference of 103 inches), you have actually traveled ____ miles

choices:

A. 33,300

B. 3,000

C. 2,700

D. 30, 330​

step 1

we know that

1 mile=63360 inches

Convert 93 in to miles

93 in=93/63360 miles

Divide 30,000 miles by 93/63360

we have

20,438,709.68 rev

Multiply by 103/63360

so

20,438,709.68(103/63360)=33,226 miles

therefore

the answer is

option A
