Answer 2

Answer:

Step-by-step explanation:

Here, the required minimum distance will be equal to the LCM of measures of their steps.

Step measure of 1st Boy = 63 cm

Step measure of 2nd Boy = 70 cm

Step measure of 3rd Boy = 77 cm

LCM of 63,70,77

LCM=2 × 3 × 3 × 5 × 7 × 11 = 6930

Hence, the minimum distance each should cover so that all can cover the distance in complete steps is 6930 cm.
