Distance = speed × time
Distance traveled by the plane flying towards north in = 1,000 x
= 1,500 km
Similarly, distance traveled by the plane flying towards west in = 1,200 x
= 1,800 km
Let these distances be represented by OA and OB respectively.
Pythagoras Theorem : It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
Applying Pythagoras theorem,
Distances between planes is 300√61 km
