The circumference of the front wheel of a cart is 30 ft long and that of the back wheel is 35 ft long. What is the distance traveled by the cart, when the front wheel has done five more revolutions than the rear wheel?  Choose the correct choice from the following answers:
A) 20 ft
B) 25 ft
C) 750 ft
D) 900 ft
E) 1050 ft
Point to note: Both the wheels would have traveled the same distance.   Now consider, no. of revolutions made by back wheel as x, which implies that the number of revolutions made by the front wheel is (x+5).   Equating the distance traveled by front wheel to back wheel: (x+5)*30 = x * 35. (Formula for calculating the distance traveled by each wheel is: # of revolutions * circumference.)   Solving this eqn. gives x=30   Sub x=30 either in (x+5)*30 or in x * 35 to get the distance, which is 1050. So the correct choice is 1050 ft.
