1.

a man travelled 60km to east of delhi then 100km to the west of it how far from delhi was he finally

Answer»

Let EAST direction be positive and west be negative.

Delhi is mean position and so let it be 0.

Since he travels 60km east,
0+60=60.

And he travels 100km west,
60-100= -40.

Negative SIGN indicates he is west of Delhi.....

THEREFORE he is 40 km west of Delhi
