Problem

Wheel A has radius

20\,\text{cm}

and wheel B has radius

30\,\text{cm}

. Both wheels turn through

5

complete revolutions. Which of the following correctly compares the linear distances

s_A

and

s_B

travelled by points on their rims? a)

s_B = \dfrac94\,s_A

s_B = \dfrac32\,s_A

s_B = \dfrac23\,s_A

s_A = s_B
