Question

An airplane flies from city b which is 80 kilometers north and 200 kilometers west of city A! How far does the plane fly (round to the nearest kilometer

Answer 1

215 km

Explanation:

If the airplane flies first north then west, then it flies 280 km.

If the airplane flies in a straight line from City B to City A, then we need to find the length of the hypotenuse of a right triangle with legs with lengths 200 km and 80 km.

c² = a² + b²

c² = (200 km)² + (80 km)²

c² = 40,000 km² + 6,400 km²

c² = 46,400 km²

c = 215 km
