315 feet

If distance=d
Number of revolutions by back wheel=d/9 & front wheel=d/7
(d/7)-(d/9)=10 ,2d=630 ,d=315

hiren vavadiya  (9 years ago)

here
7(x+10)=9(x)
solving this eq
we get x=35
now total distance =9(35)=315 feet
315

since front wheel takes 10 more revolutions so it travels 70 feet in those extra number of revolutions.
But distance travelled by front wheel is less by 2 feet as compared to rear wheel for each revolution. So this loss of 2 feet is covered by those extra revolutions taken by the front wheel.
So 70 feet would have been created by 70/2=35 revolutions.
So rear wheel travels 35 revolution (and front wheel takes 35+10=45 Revs.) So distance is 35*9 (or 45*7) = 315 feet

Distance covered=perimeter× no of revolutions. Let the rare wheel makes x revolutions so front wheel makes x+10 revolutions .Hence equation for distance covered is : 7 (x+10)=9x. Solving this we get x= 35. Hence distance covered= 35×9=315.

315, 7(x+10)=9x
x=35, 7*45 or 9*35=315
