I am about to go crazy ! Help with time ?

Question

So the question was..What time is it if you have a one handed (meaning no big hand) clock pointing to:

a. 2 marks past 2:00

b. 3 marks 3:00

c. 1 mark before 11:00

I answered.

A. 2:20

B. 3:30

C. 10:50

He then tells me this..You are on the right track with the one-handed clock, but think about 4 marks dividing 60 minutes into 5 equal parts.

I am so freaking confused please help ! $%^&

Answer 1

2:24, 3:36, 10:48

Answer 2

1.  2:24

2.  3:36

3.  10:48

If your clock is divided into 5 equal parts, each part is 12 minutes long.
