Suppose the bigger time fills up the pool in x hours, the smaller pipe fills up the pool in 1.25x.
each hour the pipe finishes 1/x portion of the job, and the smaller pipe finishes 1/1.25x portion
in 5 hours, with both pipe working, the pool is full, that is 5/x + 5/1.25x =1
5/x +4/x=1
x=9
1.25*9=11.25=11 and a quarter=11 hours and 15 minutes
it will take the slower pipe 11 hours and 15 minutes to fill up the pool.
That would be a true statement according to the lettered points. If you’ll notice, all the way around the figure, the letters are in that order. Therefore, yes it qualifies as a rectangle.

Answer:
81.5
Step-by-step explanation:
first arrange the numbers
25,40,68,70,78,85,85,95,98,100
N= 10
median= (n+1)/2
=11/2
=5.5
the average between 5th position and 6th
which is 78 and 85
=(78+85)/2
=81.5
