explain how to write 20 miles over 4 hours as a unit rate
20mi/4hrs=5mi/hr
To write 20 miles over 4 hours as a unit rate, we need to determine how many miles are traveled per hour (rate of travel). The unit rate will be expressed as miles per hour (abbreviated as mph). Here's how to calculate it:
1. Divide the total miles by the total hours:
20 miles / 4 hours = 5 miles per hour (mph)
Therefore, the unit rate is 5 miles per hour (mph). This means that, on average, you would travel 5 miles for every hour you spend traveling.
In summary, to write 20 miles over 4 hours as a unit rate, divide the total miles by the total hours to get the rate in miles per hour (mph).
