Answer:
It will take 5 weeks for Brent to catch up with Marc.
Step-by-step explanation:
Given that:
Brent knows 10 of his lines and he can memorize 8 in a week.
Marc knows 25 of his lines and can memorize 5 in a week.
L = 8w + 10 Eqn 1
L = 5w + 25 Eqn 2
As the number of lines are same,
Eqn 1 = Eqn 2
8w + 10 = 5w + 25
8w - 5w = 25 - 10
3w = 15
Dividing both sides by 3
w = 5
Hence,
It will take 5 weeks for Brent to catch up with Marc.
