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?	Choose the correct choice from the following:
A) 315	B) 325	C) 335	D) 345	E) 305
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 315NSWER:315
