49.8 km/h
Explanation:
We can determine the average speed by calculating the total distance covered and the time taken,
- First part of the trip:
v1 = 95.0 km/h = 26.4 m/s
t1 = 25.0 min = 1500 s
Distance covered:
- Second part of the trip:
v2 = 100.0 km/h = 27.8 m/s
t2 = 16.0 min = 960 s
Distance covered:
- Third part of the trip:
v3 = 40.0 km/h = 11.1 m/s
t3 = 50.0 min = 3000 s
Distance covered:
The person also spend 30.0 min without moving:
t4 = 30.0 min = 1800 s
Total distance covered:
Total time taken:
So, the average speed is
