Use a ruler. I can't see the picture.
Arranging them in ascending order :
21 , 21 , 30 , 44, 49, 52
Median = (30 + 44) ÷ 2
Median = 37 mins
------------------------------------------------------------------
Answer: Median = 37 mins (Answer D)
------------------------------------------------------------------
Answer:
You can visualize this easily.
y=f(x+h)
Now if the argument of the function is taken as (x−h) the value of y will be f((x−h)+h)=f(x)
The function y acquires the value of f(x) at (x−h) amounting to a left shift.
Hope this makes things clear.

Step-by-step explanation:
1 hour 50 minutes = 110 mins
1 1/2 hours = 90 mins
add all these:
110
90
85
55
35
when you add all these you get 375
every hour has 60 minutes
375 ÷ 60 = 6.15
if he starts at 9 am and he cleans for 6.15 hours he will be finished by 3:15pm.
