# n a morning walk three persons step of together therir steps measure 80cm 85cm 90 cm  what is the minimum distance that each should walk so that all can cover the same distance in complete steps ? what are the benifits of morning walk?

GIVEN: Their steps measure 80 cm, 85 cm, and 90 cm.

We have to find the L.C.M of the measures of their steps to calculate the required distance each should walk.

L.C.M of 80 cm, 85 cm, and 90 cm.

80=24×5

85=17×5

90=2×32×5

L.C.M(80,85,90)=24×32×5×17

=12240cm

Hence, the minimum distance each should walk so that all can cover the same distance in complete steps is 12240 cm. or 122m 40cm
