perimeter of the backwheel =9 feet,front wheel=7 feet on a certain distance ,the front wheel gets 10 revolution more than the back wheel.what is the distance

• let backwheel gets x revolution then frontwheel gets x+10 revolutions.
  both wheels will cover equal distance so..
  9x=(x+10)7
  we get x=35
  so total distance covered=9x=9*35=>315 feet

• 315 feet
  If the distance=d
  Revolution by Backwheel=d/9, frontwheel=d/7
  Given d/9+10=d/7, (d+90)/9=d/7 or d=315

• let back wheel revolution be x and front wheel revolution be(x+10)
  perimeter of back wheel=perimeter of front wheel
  9*x=7(x+10)
  9*x=7*x+70
  2*x=70
  x=35
  Distance=35*9
  =315
