The image shows a graph of distance S (in km) versus time t. The graph starts at (0,0) and goes to (0.5, 30), then to (1, 50), and finally to (1.5, 60). What is the total distance traveled in 1.5 hours?

The graph shows the distance traveled over time.

1. First segment: From t=0 to t=0.5 hours, the distance traveled is from 0 km to 30 km. The distance covered in this segment is 30 - 0 = 30 km.
2. Second segment: From t=0.5 to t=1 hour, the distance traveled is from 30 km to 50 km. The distance covered in this segment is 50 - 30 = 20 km.
3. Third segment: From t=1 to t=1.5 hours, the distance traveled is from 50 km to 60 km. The distance covered in this segment is 60 - 50 = 10 km.

Total distance traveled: To find the total distance traveled in 1.5 hours, we sum the distances from each segment.

Total distance = 30 km + 20 km + 10 km = 60 km.

Ответ: 60 км.
