Distance

Distance is the complete path covered by anything between two-point.

Displacement

However, displacement is the straight line distance bwteen two points.

Step-by-step explanation

• Since it is clear from the image attached below that the girl has covered 40meters towards the east.
• Then she moved 30 meters towards her left to reach point C.
• Time has nothing to do here with the calculation of distance.
• So, the total distance covered by her is 30+40=70 meters.
