The unit rate is 60 miles per hour.
To find the unit rate, we need to determine how much of one quantity is associated with one unit of another quantity.
Looking at the given options, we can see that the only one that provides this information is "55 miles per hour".
In this case, the unit rate is 55 miles per hour. This means that for every hour of driving, the Thompsons travel 55 miles.
To find the unit rate, we need to determine the distance traveled per unit of time.
In the given table, the options provided are:
1. 30 miles per 1/2 hour
2. 55 miles per hour
3. 60 miles per hour
4. 120 miles per 2 hours
Option 1 indicates that the Thompsons traveled 30 miles in half an hour. This can be written as 30 miles per 0.5 hours.
Option 2 indicates that the Thompsons traveled 55 miles in one hour, which can be written as 55 miles per 1 hour.
Option 3 indicates that the Thompsons traveled 60 miles in one hour, written as 60 miles per 1 hour.
Option 4 indicates that the Thompsons traveled 120 miles in 2 hours, written as 120 miles per 2 hours.
To find the unit rate, we need to divide the distance by the time.
For Option 1: 30 miles ÷ 0.5 hours = 60 miles per hour
For Option 2: 55 miles ÷ 1 hour = 55 miles per hour
For Option 3: 60 miles ÷ 1 hour = 60 miles per hour
For Option 4: 120 miles ÷ 2 hours = 60 miles per hour
The unit rate for all options is 60 miles per hour.
