Perimeter of the back wheel = 9 feet, front wheel = 7 feet on a certain distance, the front wheel gets 10 revolutions more than the back wheel .What is the distance?

• for 1 revolution:front wheel goes 7 ft.and back wheel goes 9feet.
  let distance is x feet.
  x/7=(x/9)+10
  or,2x/63=10
  or,x=(10*63)/2
  therefore,x=315

• 315 feet.
  7(f+10) = 9f
  7f+70 = 9f
  f = 35 revolutions of the front wheel
  distance = 35*9 = 315 feet
