Physics

To find the cyclist's average velocity for the entire trip, we need to determine the total displacement and the total time taken.

Calculate Total Displacement:

The cyclist travels 30 km north and then 54 km south.

The net displacement is:

Displacement=30km (north)−54km (south) = 24 km (south)

Calculate Total Time:

Time for the first segment: 2 hours

Time for the second segment: 4 hours

Total Time = 2hours + 4hours = 6hours

Then, calculate average velocity:
