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  Choose the correct choice from the following
A) 315
B) 2888
C) 270
D) 18191
E) 112
Let the backwheel made x revolutions then front wheel makes x + 10   x x 9 = (x + 10) x 7   x = 35   So distance traveled = 35 x 9 = 315   315nswer:315
