A mammalogist records that a caribou herd migrates 18 km per day during peak migration. If they cover 324 km over several days but rest every fifth day (migrating only on non-rest days), how many total days does the migration take?

How Many Days Does a Caribou Herd Take to Migrate 324 km?
A Mammalogist’s Insight into Daily Migration Patterns and Total Migration Duration Understanding the migration habits of large mammals like caribou reveals fascinating details about their survival strategies and environmental adaptation. According to recent field observations by a leading mammalogist, caribou herds migrate at an impressive rate of 18 kilometers per day during peak migration periods. For example, researchers recorded that a particular herd travels consistently 324 kilometers across their seasonal journey—but crucially, they rest every fifth day, meaning migration occurs only on non-rest days. ### The Daily Migration and Rest Cycle The key to calculating the total migration time lies in understanding the pattern:
