Question

Three boys step off together from the same spot. Their steps measure 63 cm, 70 cm
and 77 cm respectively. What is the minimum distance each should cover so that all
can cover the distance in complete steps?​

Answer 1

Answer:

6930 cm

Step-by-step explanation:

Given,

Step measure of 1st boy= 63cm

Step measure of 2nd boy=70cm

Step measure of 3rd boy= 77cm

For finding minimum distance, we have to find L.C.M of 63, 70, 77.

L.C.M. of 63, 70 and 77 = 7 x 9 x 10 x 11 = 6930 cm.

Therefore, the minimum distance is 6930 cm.
