Question

Prashanthi travels 30 km towards North then takes about turn and then travels south for 55 km. Taking North direction as positive and south direction as negative, find the prashanthi's distance from the initial starting point.

• A. 65 km towards the south.
• B. 25 km towards the south.
• C. 25 km towards the north.
• D. 50 km towards the south.

Answer 1

The correct option is B

25 km towards the south.

Distance travelled by prashanthi in north direction
= 30 km

Distance travelled in south direction
= 55 km

Prashanth's distance from the initial point
= (30 - 55 ) = -25 km

But, distance cannot be negative. So, the distance will be 25 km towards the south.
