Okay guys, here is the problem. First of all the navmap is 125KM size which 125 km = 54 mm and the time of the day is 1816. I have a convoy 79Â° from me at a distance of 170 mm on the nav map, they are on a course of 247.5Â° and travelling at 6 kts. I anticipate they have to travel along that course (247.5Â°) for a distance of 134 mm on that nav map. What time would it be when they reach that 134 km point?

Next, I plan to intercept them on a bearing of 108Â°, the distance on the nav map is 45.5mm when they have travelled 134 mm on the nav map. What time would it be when I arrive at my point if I travel at 17 kts.

6 kts/24 hrs = 267 km
17 kts/24 hrs = 756 km

Can anyone solve this for me. My brain just cannot comprehend it

Have I supplied enough information?
