About 7.07 miles
Compared to the starting point (origin), Dan is at (-4, -3) while Frank is at (1, 2).
The distances are 5 (N-S) and 5 (E-W)
x2 + y2 = 25 + 25 = 50 and sqrt (50) = 7.07 miles for the straight-line diagonal.

Two people leave simultaneously from the same starting point biking in opposite directions Linda bikes at 7 mph and Dave bikes at 9 mph how long will it be until they are 24 miles apart?
After 1 hour, Linda will be 7 miles from the starting point, and Dave will be 9 miles away from that point but in the opposite direction. So they will be exactly (9+7=) 16 miles apart after 1 hour. They are moving apart at a rate of 16 mph. After 1.5 hours they will be exactly 24 miles apart.

A train leaves at 30 mph and at the same time another train leaves at 35 mph what time will the two trains pass?
The question includes waaay not enough information.-- You have to know where they leave from. If they leave from the same place, then they pass at the time they leave.-- If they leave from different places, then you have to know how far apart the two places are.-- You have to know whether they head in the same direction (one starts behind the other and catches up)or in opposite directions (driving toward each other and meeting in the middle).
