diameter of big wheel is 50 and of small is 30.
gift find out circumference of both of them.
circumference=πd
big wheel=22×50/7
=110/7
small wheel=22×30/7
=66/7
15 rotations occurred of big wheel.
so wheel goes ............ metres.
15×110/7
=165/7m
small wheel will also gone 167/7m
rotations of small wheel = total dist. covered
----------------------------
circumference
= (167/7)/(66/7)
=167/66
167/66 rotations will take place
