Using the given information, the unit rate is 0.0645 miles/minute
<h3>Calculating rate </h3>
From the question, we are to determine the unit rate
From the given information,
Daniel runs 40/5 miles in 124 minutes
That is,
Distance = 40/5 miles = 8 miles
Time = 124 minutes
Using the formula,
Rate = Distance / Time
Rate = 8 miles / 124 minutes
Rate = 0.0645 miles/minute
Hence, the unit rate is 0.0645 miles/minute

Answer:
5 5/6
Step-by-step explanation:
Answer:
40x² + 240x + 200
Step-by-step explanation:
(10x + 10) (4x + 20) = 40x² + 240x + 200
The expression [ x² - 4 ] doesn't depend on 'a', 'b', or 'y'.
It only depends on 'x'.
You have said that 3x = 5, so x = 5/3.
Therefore, I may now write '5/3' in place of 'x' in the expression:
x² - 4 =
(5/3)² - 4 =
(25/9) - 4 =
(25/9) - (36/9) =
(25 - 36) / 9 = -11/9 = - (1 and 2/9)
