there is a circular track Amit 16 walk one round of the ground on a circular track while his wife takes 20 minutes to walk on brown suppose both of them start at the same direction after how many minutes will they meet again in the starting point
Answers
Answer:
they will take 80 minutes
Step-by-step explanation:
take the LCM of the time taken by Amit and his wife
LCM(16,20)=80
hence it would take 80 minutes to meet again at the starting point
Complete question:
There is a circular track. Amit takes 16minutes to walk one round of the ground on the circular track while his wife takes 20 minutes to walk on the circular track. suppose both of them start at the same direction after how many minutes will they meet again in the starting point
Answer:
Amit and his wife meet again after 80 minutes
Step-by-step explanation:
Given,
Amit takes 16minutes to walk on the circular track
his wife takes 20 minutes to walk on the circular track
Both Amit and his wife started at the same direction
To find,
After how many minutes will they meet again
Solution:
The time in which they meet again is the LCM ( 16, 20)
Prime factorization of 16 = 2×2×2×2
Prime factorization of 20 = 2×2×5
The least common multiply of 16 and 20 = 2×2×2×2×5 = 80
LCM(16,20) = 80
∴ Amit and his wife meet again after 80 minutes
