Answer:
The correct answers are
Sal walks 14 km in 4 h
Sal walks 3.5 km in 1 h
Step-by-step explanation:
Given:
Distance represented by Y axis in kilometer.
Time represented by X axis in hour,
The graph of line is showing distance walked. And the two points are (1, 3.5) and (4, 14).
In plotting of points the first coordinate is always the X coordinate that is time in hour here, and the second coordinate is always the Y coordinate that is distance in km.
Therefore, the given below two options are correct
Sal walks 14 km in 4 h
Sal walks 3.5 km in 1 h
The first partner in the handshake can be any one of 15 people.
The second partner can be any one of 14 people.
So the total number of possible arrangements is (15 x 14) = <u>210</u> .
<em><u>BUT . . . .</u></em>
If Mr. Smith and Mr. Jones are shaking hands, it doesn't matter which one is the first partner and which one is the second partner ... It's the same handshake either way.
That number of ' <u>210</u> ' up above counted both ways separately. The real number of handshakes <em>between different people</em> is half of that 210/2 = <em>105 handshakes</em>.
