Answer:
Step-by-step explanation:
This question is seeking to find the LCM of the three numbers.
We will use the factor method to find the LCM of the numbers.
We do this by writing the numbers as a product of their prime factors.
30 = 2 × 3 × 5
36 = 2 × 2 × 3 × 3
40 = 2 × 2 × 2 × 5
LCM = 2^3 × 3^2 × 5
= 360
The minimum distance = 360 cm
This gives the LCM of the three numbers and it is the minimum distance.
