Read Solution (Total 2)
-
- 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 - 13 years agoHelpfull: Yes(18) No(0)
- 315 feet.
7(f+10) = 9f
7f+70 = 9f
f = 35 revolutions of the front wheel
distance = 35*9 = 315 feet
