Step-by-step explanation:
1. The end time on the graph is 150 minutes. That is ...
(150 min)(1 h)/(60 min) = (150/60) h = 2.5 h
It took Bella 2.5 hours to reach the grocery store.
__
2. Bella is stopped at the places in the curve where the vertical coordinates are not changing. That is, where the graph is horizontal. The total time that the graph is horizontal is 10 min + 20 min = 30 min.
Bella was on the phone for 30 minutes.
__
3. Bella walked 5 km in the first 50 minutes, 2 km (toward home) in the next 20 minutes, and 3 km in the last 60 minutes before she got to the grocery store. Her total distance was ...
5 km + 2k + 3 km = 10 km
Bella traveled a total of 10 km.
