Step-by-step explanation: see attachment
1. You have that the speed is:

Where
is the distance and
is the time.
2. Tory pilots her boat
before docking, therefore, his time is

3. Emilio continues for another
, with a total of
before docking. Therefore, his time is:

4. And his speed is:

5. Solve for
and substitute the value into the formula of Tory's time:

The answer is: 
D because if it’s liner then it’s probably positive... I’m not sure
Answer:
3/4 meter
Step-by-step explanation:
Need Common denominators to compare size
2/6 3/4 4/9 which is longer than 2/3?
2/6 compared to 2/3. 2/6 = 2/6 and 2/3 = 4/6.
2/6 < 2/3 so 2/6 is too short
3/4 compared to 2/3 3/4 = 9/12 and 2/3 = 8/12
3/4 > 2/3 so 3/4 is longer than 2/3
4/9 compared to 2/3 4/9 = 4/9 and 2/3 = 6/9
4/9 < 2/3 so 4/9 is too short
This is deductive reasoning.
Hope you have a nice day! :)
