Question

the circumference of the front wheel of a cart is 3 cm long and that of the back wheel is 4 cm long what is the distance travelled by the cart when the front of wheel five more Revolution then the real wheel

Answer 1

let x be the revolution done by the real wheel

from that 4x ,3x are two wheels traveled by x revolution


but front wheel is small it has to rotate 5 more times

5×3

=15cm
they travel only the same distance.
front wheel t distance traveled=back wheel
so, 3x+15=4x

x=15

the distance traveled by the cart =
3×15+15or 4×15


=60cm
