Question

1. In what period did the boat travel the fastest?
2. In what period did the boat travel the slowest?
3. How many total days did the boat rest?

Answer 1

Answer:

Explanation:

1) The steepest slope occurs for 0 < t < 1 days advancing 10 km/day

2) The slope is lowest (0 or no advancement) for

1 < t < 3 days

and

6 < t < 10 days

If the question means slowest speed but not stopped, then the lowest non zero slope occurs in 11< t < 14 advancing 5 km/day

3) (3 - 1) + (10 - 6) = 6 days
