Question 40592: Joanne sets up her Ninja turtles in a big circle with each turtle spaced an equal distance from its neighbors. She then proceeds to count them in order around the circle. Unfortunately, she loses track of where she started before she finishes counting. But she realizes that she can still figure out how many turtles are in the circle by noticing that the sixth turtle is directly opposite the 17th turtle. How many Ninja turtles are in the circle?

Question 40591: How many 9 onch square floor tiles are needed to cover a rectangular floor that measures 12 ft. by 15 ft.
12x12=144 inches
12X15=180 inches
Each tile 9 inches
9 divided into 144=16
9 divided into 180=20; 16 X 20= 320 tiles
Is this right?

Question 40593: Call Betty as B, Isabel as I and so on.
Draw a horizontal straight line and mark any point on it and name it U (as the name of Ursula features twice in the problem).
This is the position of Ursula.
Assume all the runners are going left to right.
Now mark the point B to the left of U as Bethy finished behind Ursula.
Distance between B and U is 30 cm (12 in = 30 cm).
In the same way mark the points A and L and note their distances from U and A are 7.5 cm and 500 cm respectively.
Nothing is mentioned about Isabel.
So assume that she is neither first nor last.
From the figure you draw it is clear that U is first and L is last.
Find from the figure, distance between U and L = 507.5 cm.
As C finished half way between the first and last person, so mark C on the figure as the mid-point of the line segment UL.
Note: LC = UC =  = 253.75 cm.
Forget about Isabel.
Look at the figure and you will be able to tell that U finished first, then A, then B, then C and then L at last.
Distance between two women is the length between the points marked with the first letters of their names.
Note AU = 7.5 cm, AB = 22.5 cm, BC = 223.75 cm and BL = 253.85 cm.
Well, no comment on Isabel unless any further data is given.

Question 40843: Let the first biker left the ranger station at 'x' hrs.
Then by 4 pm he rode for ((4+12) - x) = (16 - x) hrs.
Distance traveled by him =  miles.
The second biker left the ranger station 1 hr after the first biker.
So he traveled for ((16 - x) - 1) = (15 - x) hrs.
Distance traveled by him =  miles.
As both bikers met at 4 pm so by then they have travelled equal distances.
So 
Solving we get x = 13.
Thus the first biker left the ranger station at 13 hrs or 1 pm.

Question 40647: Call the places by the first letter of their name e.g. Arachnid by A, Feline by F and so on.
The notation A->F means travelling from A to F and AF denotes distance traveled by going from A to F or F to A.
/
First: shortest(FB) = ?
F->B can be either F->T->B or F->L->B.
In first case FB is (6 + 9) = 15 miles and
in the second case FB is (11 + 12) = 23 miles.
Clearly 15 < 23. So shortest path is F->T->B and corresponding distance = 15 miles.
/
Second: shortest(LT) = ?
L->T can be either L->F->T or L->B->T.
In first case LT is (11 + 6) = 17 miles and
in the second case LT is (12 + 9) = 21 miles.
Clearly 17 < 21. So shortest path is L->F->T and corresponding distance = 17 miles.
/
Third: shortest(CF) = ?
C->F can be either C->L->F or C->A->T->F or C->B->T->F.
In first case CF is (3 + 11) = 14 miles,
in second case CF is (15 + 1 + 6) = 22 miles and
in third case CF is (7 + 9 + 6) = 22 miles.
Clearly 14 < 22. So shortest path is C->L->F and corresponding distance = 14 miles.
/
Do the rest of the problem yourself following the procedure above.
The answers of fourth part onwards are 18, 16, 12 and 7 miles respectively.
