"10-minute" vs "10 minutes" are both the same amount of time, so what's the difference between them? The simple answer? The former is an adjective and the latter is a noun. Look at the examples below:
It takes 10 minutes to walk from home to school. (10 minutes is an amount of time)
I have a 10-minute walk from home to school. (10-minute describes the amount of time)
Notice that "minute" takes the plural form as a noun, but not as an adjective. The same applies for any measurement of time:
The Detroit Red Wings ended their 42-year championship drought when they won the Stanley Cup in 1997.
After 42 years without a championship, the Detroit Red Wings won the Stanley Cup in 1997.
