Final answer:
The rate is 5 laps per minute, which is the unit rate as well. The rate unit is 'laps per minute'. The process involves dividing the number of laps by the number of minutes.
Step-by-step explanation:
The ratio of the number of laps to the number of minutes is given as 15 to 3. To find the rate, we can divide the number of laps by the number of minutes:
- Divide 15 laps by 3 minutes to get the rate, which is 5 laps per minute.
- The unit rate is the rate for one unit of time, which in this case is already calculated as 5 laps per minute (since minutes are already “at 1”).
- The rate unit in this scenario is laps per minute.
To review adding units of time:
- 15 minutes + 60 minutes = 75 minutes
- 10 minutes + 20 minutes = 30 minutes
- 15 seconds + 45 seconds= 60 seconds, which is also 1 minute
A rate is how a quantity relates to another over a period of time. For example, velocity changes per unit time or concentration changes per unit time. Ratios can be written in various forms such as fractions, colons, or the word "to." A proportion is when two ratios are equivalent. A unit rate is a rate where one of the measurements is 1. The unit scale on a map is a ratio that represents the dimensions of an object compared to its representation on the map.
