It took a racer 300 second to run 3,000 meters. Based on the ratio given and using a double number line, how long did it take the racer to run 2,000 meters? (if you can, use a paper to draw the double number line, thank you)

200 seconds

1:2 ratio for 2,000 meters and 1:3 ratio for 3,000 meters

Step-by-step explanation:

It takes the racer 100 seconds to run 1,000 meters and there is 3'000 meters so you multiply 100 times 3 to get 300.

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
