The unit rate of the car is simply the average speed of the car between the two points.
The unit rate of the car is 40 miles per hour
From the diagram (see attachment), we have:
- The distance between the two points is: 80 miles
- The time spent to cover this distance is: 2 hours
<h3>The unit rate</h3>
So, the unit rate is:
This gives
Simplify the quotient
Hence, the unit rate of the car is 40 miles per hour

Suppose that the farmer had bought the rice at x dollars per bag and had sold them at a 25% markup. How much did the bags cost him before he added the markup? 1.25x =$75 results in $75/1.25, or $60 per bag.
If he sold 25 bags, his profit would be 1.25($60/bag)(25 bags) = $1875.
I very seriously doubt that the rice was $7500 per bag. Perhaps you meant $75/bag...?
Answer:
Standard error of the proportion = 0.04702
Step-by-step explanation:
<u>Explanation</u>:-
According to a survey by the Better Sleep Council, 33% of people admit to dozing off at their workplace
The sample proportion p = 33% = 0.33
q = 1-p = 1-0.33 = 0.67
Given a random sample of 100 workers is selected from this population
Given sample size 'n' = 100
The standard error of the Proportion is determined by
<u>Final answer</u>:-
Standard error of the proportion = 0.04702
Answer:45 mins.
Step-by-step explanation: half of 30 is 15 (one box = 15) and 15 times 3 is 45
