Hi ,

diameter of the wheel ( d ) = 70cm

radius ( r ) = d/2 = 70 /2 = 35 cm

distance moved by 1 revolution = circumference of the wheel

= 2πr

= 2 × 22/7 × 35

= 2 × 22 × 5

= 220 cm

220cm moves in 1 revolution

1km = 100000 cm moves in x revolutions

x = ( 100000 /220 )

x = 10000/22 revolutions

I hope this helps you.

:)
