Answer:
1. 213.33 m/min
2. 166.67 m/min
3. Between t = 3 and t = 3.75
Explanation:
Average velocity is the change in position over the change in time.
vₐ = (s₂ − s₁) / (t₂ − t₁)
1. From t = 0 to t = 7.5, the average velocity is:
vₐ = (1600 m − 0 m) / (7.5 min − 0 min)
vₐ = 213.33 m/min
2. From t = 1.5 to t = 4.5, the average velocity is:
vₐ = (850 m − 350 m) / (4.5 min − 1.5 min)
vₐ = 166.67 m/min
3. The table is divided into equal time increments. Between t = 3 and t = 3.75, the position increased by 100 m, which is less than any other increase. This is also where the slope is the shallowest on the graph.
