Answer:
The Coefficient is 3
Step-by-step explanation:
Refer to the diagram shown below.
The velocity of the person on the walkway relative to the ground is the velocity of the walkway (relative to the ground) plus the velocity of the person relative to the walkway.
It is
1.0 + 0.5 = 1.5 m/s
The person on the ground moves at - 0.2 m/s, which is in the opposite direction to that of the walkway and the person on the walkway.
Therefore the velocity of the person on the walkway relative to the person on the ground is
105 - (-0.2) = 1.7 m/s
Answer: 1.7 m/s
4(3+5) --> this means that 12/4=3 and 20/4=5 and 4 is the GCF
7.5 hours total divided by .5 hours per arrangement would be 15 arrangements.
