how much time did susan spend moving toward her office?
min

The question is asking how much time Susan spent moving toward her office.  On the graph, the y-axis represents the distance Susan is from her office, so the amount of time she is moving toward her office is the amount of time the graph is going down.

As you can see, the graph is going down from the 10 to 16 minute marks and the 22 to 26 minute marks.  In total, this is 20 minutes in which the graph is going down.

Therefore, Susan spends 20 minutes moving toward her office.

I’m not absolutely sure but i think it’s 7x6x5x4x3x2=5040 because as the first character you can take any of the 7 given then you are left with 5 then 6 then 4 etc.
