Hi Rebeck and Chandan smile

2. It's simply two 30-60-90 triangles. Initially the side opposite to 30 degree is 100 km that means the hypotenuse i.e. distance between the air-crafts is 2*100 = 200 km initially.
After half an hour, the side opposite to 60 degree is 100 km that means the hypotenuse i.e. distance between the air-crafts will be 200/30.5 ~ 115.47 km. smile
