Step-by-step explanation:
12 = 2 × 2 × 3
18 = 2 × 3 × 3
56 = 2 ×2 × 2 × 7
Now
Common factor = 2
Remaining factor = 2 × 3 × 2 × 3 × 7
LCM = RF × CF
= 504
hence the lCM of 12 , 18 and 56 is 504...

Answer:
1.83 hours
Step-by-step explanation:
Time is inversely proportional to speed
Implies that T = k/R, where k is the constant of proportionality
Thus, the product T × R is a constant for any given valued of R,T.
Hence, 3 × 14 = t × 23
t = (3×14) ÷ 23
t = 1.83 hours
