Answer»

Answer:

1386 seconds later

Step-by-step explanation:

If they continue with same speed they will meet after 1386 seonds from start

CALCULATE LCM

Decompose all numbers into prime factors

126 - 2 3 3 7

154 - 2 7 11

198 - 2 3 3 11

Write all numbers as the product of its prime factors

Prime factors of 126 = 2 . 3^2 . 7

Prime factors of 154 = 2 . 7 . 11

Prime factors of 198 = 2 . 3^2 . 11

Choose the common and uncommon prime factors with the GREATEST EXPONENT

Common prime factors: 2

Common prime factors with the greatest exponent: 2^1

Uncommon prime factors: 3 , 7 , 11

Uncommon prime factors with the greatest exponent: 3^2, 7^1, 11^1

Calculate the Least Common Multiple or LCM

1386
