The answer is 17.8 km in North-East direction

GIVEN

Salil travels 9 km towards East, then 8 km towards North, and finally travels 7 km towards East.

TO FIND

How far is he from his original place and in which direction.

SOLUTION

We can simply solve the above problem as follows;

Let the starting point of Salil be 'A'

Distance travelled to East = AB = 9 km

Distance travelled to North direction = BC = 8km

Distance travelled to East direction = CD = 7km

Distance from his orignal place = AD

Now produce AB to E

such that,

BE = CD = 8 km

Similarly, Join D to E

Therefore,

DE = CB = 9km

Now,

Applying Pythagorus theorem in ΔADE

AD² = AE² + DE²

AD² = 16² + 8²

AD² = √320

AD = 17.8 km

The direction is North-East

Hence, The answer is 17.8 km in North-East direction
