Hello Darshan.
When you find speed, you can use the formula: speed = distance/time
You need distance between points A and C; You can use the Pythagorean Theorem for that
a^2 +b^2 = c^2; 300^2 + 60^2 = c^2; 90000+ 3600 = c^2; c is about 305.9
the plane travel this in 1 hour; 305.9/1 = 305.9
it goes to the north east with a speed of 305.9
hope that helps

Lets say Agle A is a, Whe know that Agle B is 90; you can use sin Theorem so side a =60, side b = 305.9, angle B is 90 sine a/side a = sine 90/side b sine a/60 = 0.89/305.9 please solve this proportion and you will get an angle. The agles are 37,53,90 for most pythagoren triangles so it should be 37 but you can still solve and check
