Answer 1

Answer:

girl's home is .12km

Hence, the total distance covered in the round trip is .12+12=24km

Total time taken to cover the round trip is given as .7hr 30min=7.5hrs

As the initial position and the final position of the girl are same, the net displacement of the girl is zero.

Average speed is given as,

Average speed =Total distance/Total time taken=24km/7.5hrs=3.2kmh1/2

Average velocity is given as,

Average velocity= Net displacement/Total time taken=okm/7.5hrs 0km h 1/2
