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
