Answer:

yes

Explanation:

A unit rate is a ratio that shows how many of one unit of measurement corresponds to a single unit of another type of measurement. The per in 'miles per hour' makes it a rate, and the singular hour makes it a unit rate.

Examples:

  • Unit rate: 45 miles per hour
  • Unit rate: 60 seconds per minute
  • Unit rate: $10k per month
  • Not a unit rate: 90 miles per 3 hours
  • Not a unit rate: 240 seconds per 4 minutes
  • Not a unit rate: $50k per 6 months

Those last 3 are not unit rates because the second unit is not singular. They can be simplified to a unit rate though:

  • Not a unit rate: 20 x per 5 y
  • Simplified to unit rate: 4 x per y
