<span>1. In how many games does a girl play against a boy?
A: Because there are 5 girls, each will play against 5 boys, so in total is 5*5 = 25 times.
2. </span><span>In how many games does a girl play against another girl?
A: In this case, we only need to calculate how many girl pairs are there among these 5 girls, and it become a combination problem which can solved by </span>

3.The fraction of games "B vs B" should be the number of "B vs B" (which is 10) divide the total number of the games "B vs B" & "G vs G" & "B vs G" (which is 10+10+25=45, see the analysis in 1.A and 2.A), so the fraction should be 10/45=2/9
4.One person will have to play against 9 people at the tournament, and the total number of the games is 45, so the fraction should be 9/45 = 1/5
Greetings!
The second option would be correct as the sales in January and June were both at $240,000, based of the graph.
Hope this helps.

Answer:
Step-by-step explanation:
Given as :
The distance cover while running =
= 5 miles
Let The speed for running = 
The distance cover with bike =
= 80 miles
The speed for biking =
= 15 mph + 
Total Time taken = 5 hours
Now Time = 
∴ 5 hour =
+ 
Or, 5 hour =
+ 
Or, 5 hour = 
or, 5 × (
) = 
Or,
-
= 0
or,
= 0
or,
= 0
Or,
= 0
Or,
= 0
Or,
= 0
∴
= 3 , - 5
So, the running speed = 3 mile per hour
And the biking speed = 15 mph + 3 mph = 18 mile per hour
Hence The running speed of Stu is 3 mile per hour . Answer
