Answer:

1) 250 meters= 0.25 km

2) 12 meters= 0.012km

3) 1 meter= 0.001 km

The constant of proportionality is 1000 meters in 1km (1000 meters)

I think there’s a mistake on the second part because 1 meter does not equal to 1000km. but I did part 1 for you!

What is the rate of change of the water level , in feet per hour

miskamm [114]

A; rate of change is the same as slope, so, using the slope formula, $m= \frac{y_{2} - y\1_{1} }{ x_{2} - x_{1} }$ , where $m$ is the slope and $x_{1}$ , $x_{2}$ , $y_{1}$ , and $y_{2}$ are the $x$ and $y$ values.

Plug in $2$ points for $x$ and $y$ , water level being the $y$ and time being the $x$ since we're looking for the answer in ft/hr-- you can choose any two, but from the same row.

$m= \frac{ 30-50}{4-0}$
$m= \frac{-20}{4}$
$m= \frac{-5}{1}$
$m= -5$ ft/hr
