I'm not sure if you are still trying to solve this but here is how I would do it.
I will define the variable 't' = "the time spent traveling"
As you may already know your problem describes a right angle triangle with the following sides:
1. A = Long side adjacent to the 90° = 500
2. B = Short side adjacent to the 90° = 3.7·t (or 3.7 times 't')
3. C = Hypotenuse = 10·t
Setting up the standard equation for a right angle triangle (Pythagoras Theorem) A^2 + B^2 = C^2 gives the following relation ship (the '^' hat symbol indicates "raised to the power of" so that each side is squared):
Equation: 500^2 + (3.7·t)^2 = (10·t)^2
Steps to solve: 250,000 + 13.69·t^2 = 100·t^2
250,000 = 86.31·t^2
t^2 = 250,000/86.31 = 2896.54
t= 53.8 seconds
Solving for the angle is easy if you use the sine function. I'll define "theta" as the angle of traverse.
sin(theta)= opposite/hypotenuse = (3.7·t)/(10·t)= 0.37
so theta = asin(3.7) = 21.72°
You could also use cosine or tangent but you have to multiply 't' into one of the velocities which is slightly longer math.
I hope this helps.
