Answer:
Day Distance Time Rate
Tuesday 4 38 9.5
Wednesday 6 72 12
Thursday 4 37 9.25
Saturday 3 31.5 10.5
Sunday 12 138 11.5
On Thursday, she ran 1 mile in 9.25 minutes, which is the fastest speed.
Step-by-step explanation:
Consider the provided table.
We need to find the unit rate.
Unit rate is the time taken to run one mile. Here the unit rate is the number of minutes divided by the number of miles for each day.
Consider the table:
For Tuesday:
Distance is 4 miles and time is 38 minutes
The unit rate is: 38 ÷ 4 = 9.5 minutes to run one mile
For Wednesday:
Distance is 6 miles and time is 72 minutes
The unit rate is: 72 ÷ 6 = 12 minutes to run one mile
For Thursday:
Distance is 4 miles and time is 37 minutes
The unit rate is: 37 ÷ 4 = 9.25 minutes to run one mile
For Saturday:
Distance is 3 miles and time is 31.5 minutes
The unit rate is: 31.5 ÷ 3 = 10.5 minutes to run one mile
For Sunday:
Distance is 12 miles and time is 138 minutes
The unit rate is: 138 ÷ 12 = 11.5 minutes to run one mile
On Thursday, she ran 1 mile in 9.25 minutes, which is the fastest speed.
