The helicopter flying in a straight line for 400 km turned at an angle of 90 * and flew another 300 km, find the path and movement of the helicopter.
1. The route traversed by the helicopter will consist of two parts and will be: 400 + 300 = 700 km.
2. The movement of the helicopter will be equal to the length of the hypotenuse of a right-angled triangle with legs measuring 400 km and 300 km. Let’s find the length of the hypotenuse by the Pythagorean theorem: √ (4002 + 3002) = √ (160000 + 90000 = √250000 = 500 km.
Answer: the path of the helicopter is 700 km, the movement is 500 km.
