Perimeter of front wheel =30, back wheel = 20. If front wheel revolves 240 times. How many revolutions will the back wheel take?
Read Solution (Total 5)
-
- sice the distance covered by both the wheels should be same
so
let x be the no. of revolutions by the back wheel
so 240*2*pie*30=x*2*pie*20
so x=360. - 13 years agoHelpfull: Yes(6) No(0)
- Assume revolution of back wheel is X and here 240*30=7200 so 20*X=7200 and X=360..
so 360 is answer...
- 13 years agoHelpfull: Yes(5) No(0)
- revolution of back wheel is X
therefore 240*30=x*20
7200 =20x
x= 360
so the answer is 360 - 11 years agoHelpfull: Yes(2) No(0)
- 240/30*20 = 360 times
