Answer:
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
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

Answer:
The minimum distance each should walk so that all can cover the same is 12240cm
Explanation:
To get the answer, we must find the LCM of 80, 85 & 90
LCM (80,85,90) = 12,240cm (or) 122.4 m
