Question

The wheels on a car have a diameter of 28 inches. How many full revolutions will the wheels need to make to travel 200 feet?

Answer 1

Given

diameter of the wheel =28''

so radius=14''

Now , distance covered by the wheel in 1 revolution =2 pie r

=》2×22/7×14''

=》44×2''

=》88''

Now given distance =200'

=200×12''

=2400"

Therefore, required no. of revolutions = 2400"/88"

=27.27

so required no. of full revolutions should be 28(approximately).
