Answer» We have to find the LCM of 40 cm, 42 cm and 45 cm to get the required minimum distance. Because we are asked the minimum distanceNow,40 = 2 × 2 × 2 × 5,42 = 2 × 3 × 7 45 = 3 × 3 × 5 ∴ LCM (40, 42, 45) = 2 × 3 × 5 × 2 × 2 × 3 × 7 = 30 × 12 × 7 = 210 × 12 = 2520 Minimum distance each should walk 2520 cm. so that, each can cover the same distance in complete steps. |
