1.8 will be your answer 3*3=9 and 9/5=1.8
Answer:
2 miles = 3218.6m
3km = 3000m
ATQ, 2 miles - 3km = 3218.6m - 3000m =
<em><u>218.6m</u></em>
The average is pretty simple to find. Add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
The answer to this specific question can be modeled as 
. After simplifying everything, you would get x 
77, so Justin has to get at least a 77 to get a 75 average.
Part a), solve this system of equations:
x + y = 5
x - y = 2.25
2x = 7.25
x = 3.625
y = 1.375
part b), solve this system of equations:
x + y = 5
x = 3y
y = 1.25
x = 3.75
