The struggle is real. Someone help me out here please:

>5. Two old ladies left from A to B and from B to A at dawn heading to-wards one another (along the same road). They met at noon, but did not stop, and each of them carried on walking with the same speed. The first lady came (to B) at 4pm, and the second (to A) at 9pm. What time was the dawn that day?

I think dawn was at 6am. This assumes that Old Lady A travels the full distance in 10 hours and Old Lady B takes 15 hours to travel the same distance.

I don't know how I arrived at that answer other than some sort of trial and error. I don't like it.

Any advice?
