A, B and C start at the same time in the same direction to run around ...
Given:
- A completes a round in 252 seconds
- B completes a round in 308 seconds
- C completes a round in 198 seconds
To find:
- After what time will they again at the starting point?
Solution:
To find the time at which they will again meet at the starting point, we need to find the least common multiple (LCM) of the given times taken by A, B, and C to complete one round.
Step 1: Prime factorization of the given times:
- 252 = 2 * 2 * 3 * 3 * 7
- 308 = 2 * 2 * 7 * 11
- 198 = 2 * 3 * 3 * 11
Step 2: Finding the LCM:
The LCM is obtained by taking the highest powers of all prime factors involved.
- LCM = 2 * 2 * 3 * 3 * 7 * 11 = 2772 seconds
Step 3: Converting the LCM to minutes and seconds:
- 2772 seconds = 2772 / 60 minutes (quotient) + 2772 % 60 seconds (remainder)
- 2772 seconds = 46 minutes + 12 seconds
Therefore, they will meet again at the starting point after 46 minutes and 12 seconds. Hence, the correct answer is option D.
- A completes a round in 252 seconds
- B completes a round in 308 seconds
- C completes a round in 198 seconds
To find:
- After what time will they again at the starting point?
Solution:
To find the time at which they will again meet at the starting point, we need to find the least common multiple (LCM) of the given times taken by A, B, and C to complete one round.
Step 1: Prime factorization of the given times:
- 252 = 2 * 2 * 3 * 3 * 7
- 308 = 2 * 2 * 7 * 11
- 198 = 2 * 3 * 3 * 11
Step 2: Finding the LCM:
The LCM is obtained by taking the highest powers of all prime factors involved.
- LCM = 2 * 2 * 3 * 3 * 7 * 11 = 2772 seconds
Step 3: Converting the LCM to minutes and seconds:
- 2772 seconds = 2772 / 60 minutes (quotient) + 2772 % 60 seconds (remainder)
- 2772 seconds = 46 minutes + 12 seconds
Therefore, they will meet again at the starting point after 46 minutes and 12 seconds. Hence, the correct answer is option D.
