Distance covered while flying in north-east direction = 20.0 km
Distance covered while traveling in the east direction = 30.0 km
Distance covered while traveling in the north direction = 10.0 km
According to the figure,
Distance traveling from B to C,
tan 60° = BC / 20
BC = 20√3
Using Pythagoras' theorem,
Distance covered from A to C,
AC² = AB² + BC²
AC² = 40² + (40√3)²
AC² = 1600 + 4800
AC = √6400
AC = 80.0 km
Similarly, the Distance covered from C to E
CE² = CD² + DE²
CE² = 30² + 10²
CE² = 900 + 100
CE = √1000
CE = 10√10 km
Total distance covered from starting point
= 80 + 10√10
= 80 + 30.16
= 110.16 km
