3.2 Kilometers

reasoning:

there are 1000 meters in a kilometer. If they march 800 meters in 15 minutes, in 60 minutes they will march 3200 meters (800x4) . You then divide 3200 by 1000 to get 3.2 kilometers

$C. \ t=\frac{8.75}{v}$

Step-by-step explanation:

Given the time t it takes for a group of volunteers to clean up a park varies inversely with the number of volunteers v.

Therefore, we could write in inverse relation between t and v as

$t=\frac{k}{v}$ , where k is the constant of proportionality.

We also given if it takes 7 volunteers 1.25 hours to clean up the park.

Therefore, plugging t=1.25 and and v=7 in above inverse relation, we get

$1.25=\frac{k}{7}$

On cross multiplying, we get

$1.25 \times 7 = k$

k= 8.75.

So, we got value of the constant of proportionality = 8.75.

Plugging k= 8.25 in inverse relation, we get

$t=\frac{8.75}{v}$ , which is c option.
