Question

To some Marines one cruising at 25 kn in the other 20 kn left the naval base at the same moment. Three hours later they were 100 nautical miles apart. What is the measure between their horses ?

Answer 1

I believe you would have to multiply both 25 and 20 and what ever number you get dived by 100 if the numbers to high multiply aging or subtract the number (if it's wrong I'm really not good at my math I'm sorry)
