Question

Three people go for a morning walk together. Their steps measure 70cm, 84cm and 105cm respectively. what is the minimum distance traveled when their steps will exactly match after starting the walk assuming that there walking speed is same?​

Answer 1

Answer:

12240 cm.

Step-by-step explanation:

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 i.e. 80 cm, 85 cm, and 90 cm, to calculate the required distance each should walk.

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

80 = 2⁴ x 5

85 = 17 x 5

90 = 2 x 3 x 3 x 5

L.C.M of 80, 85 and 90 = 2⁴ x 3 x 3 x 5 x 17

L.C.M of 80, 85 and 90 = 12240 cm

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