Answer:
- Leroy Sands & Walt Smith - green
- Frank Cook & Phil Hawley - yellow
- Paul O'Brien & Alan Wilson - blue
- Henry Gladstone & Don Hughes - red
Step-by-step explanation:
First of all, it is convenient to choose the false statement.
We note that statements 7 (Alan is first) and 10 (Alan did not finish) are contradictory, so one of them must be false. Statement 5 has Henry & Hughes together, so is not consistent with statement 7 (Alan & Hughes). So, statement 7 is inconsistent with two other statements, thus must be the false one.

The attached table shows how we parsed the statements. An "O" signifies a combination that must occur; and "X" signifies one that cannot occur. We have used "-" to fill the spaces that are inconsistent with the locations of "O". The red letters are deduced from the others.
The first complete set we found was Henry & Hughes (Don & Gladstone) who were in the (red) capsized raft and did not finish. The second complete set we found was Phil & Cook (Frank & Hawley) who were in the (yellow) raft that finished second. We know Paul & Wilson (Alan & Partner) finished last, so Phil & Cook could not have been Paul and Wilson. Finally, O'Brien and Leroy were not on the same boat, so Paul must be Paul O'Brien and Leroy must be Leroy Sands.
Answer: No the graph fails the vertical line test.
Step-by-step explanation:
One time because 50 x 50 equals 100 and that to large
1. 2x
2. (230-x)
Step-by-step explanation:
<u>Step 1 </u>:
- If 'x' represents the feet distance that has been covered since Brian started walking towards Maggie then the expression can be given as,
= 2x
Since the distance is covered by 2 walkers and hence the total distance will be 2x
<u>Step 2</u> :
- The distance in feet between Maggie and Brian is given to be 230 ft and hence the distance in feet is given by the expression,
= (230-x)
(230 - x) is the distance covered in feet.
