Marcus' Exam Question
I'm just watching this episode and I'm wondering if it is worth putting the answer to Marcus' Exam question in the Misc. Trivia section.

The question is: An older brother leaves home to go to school which is 2 kilometres away from his house. 10 minutes later, his younger sister chases him after using the same road. The older brother walks 80 metres per minute, while the sister runs 200 metres per minute. How many minutes will it take for the sister to reach her brother?

By my calculations, the answer is 16m 40 s.

80m = 200(m-10) (2/5)m = m-10 (2/5) = 1-(10/m) ((2/5)-1)=-10/m (-3/5)=-10/m (3/5)m=10 m = 10(5/3) m = (50/3) m = 16.666666666~
