The question is basically asking for the difference between how far ryan lives from the store and how far abby lives from the store.
therefore, to solve the problem, we can just do: distance ryan lives from the store minus distance abby lives from the store.
since ryan is 3.76 kilometers from the store and abby is 1.67 kilometers from the store, the answer is:
3.76 - 1.67 = 2.09 kilometers.

Answer:
16 days
Step-by-step explanation:
24 men works 8 hours a day to complete a work in 15 days. While 20 men works at 9 hours per day to complete the same work in x days. We can find the number of days it took the 20 men by using the expression below:
24 men * 8 hours/day * 15 days = 20 men * 9 hours/day * x days
Therefore it took 20 men working 9 hours/day, 16 days to complete the same work

Answer: 4/25
=========================================
Explanation:
Let's define two events A and B
A = event of selecting red on the first draw
B = event of selecting red on the second draw
P(A) is the notation that means "probability of event A occurring"
P(A) = 2/5 because there are 2 red marbles out of 5 total (2 red + 3 black = 5)
Similarly, P(B) = 2/5 as well because A and B deal with the same color red, and because Abby put the first marble back
Multiply the probabilities
P(A and B) = P(A)*P(B) ... see note below
P(A and B) = (2/5)*(2/5)
P(A and B) = (2*2)/(5*5)
P(A and B) = 4/25 which is the answer
Note: the equation used is only valid if events A and B are independent, which they are in this case. The fact we put the marble back means the chances of picking red are the same as before.
