On a morning walk, three persons step out together and their stepsmeas

1.	On a morning walk, three persons step out together and their stepsmeasure 30 cm, 36 cm and 40 cm respectively. What is the minimumdistance each should walk so that each can cover the same distance incomplete steps ?
Answer» Minimum distance = LCM of 30,36,40 therefore , 30 = 2×3×5 36 = 2×2×3×3 40 = 2×2×2×5 Thus the LCM of 30,36,40 = 360 Therefore the minimum distance each should walk = 3 m and 60 cm. therefore the minimum distance it should walk is 3 m 60 cm

Answer»

Minimum distance = LCM of 30,36,40

therefore ,

30 = 2×3×5

36 = 2×2×3×3

40 = 2×2×2×5

Thus the LCM of 30,36,40 = 360

Therefore the minimum distance each should walk = 3 m and 60 cm.

therefore the minimum distance it should walk is 3 m 60 cm
