Half of 72 is 36. If you divided 36 by 4, you would get 9. So, s = 9 and means that it takes 9 seconds for the rock to be sunk half way.

Harvey rides his bike at an average speed of 12 miles per hour. In other words, he rides 12 miles in 1 hour, 24 miles in 2 hours
timama [110]

Answer:

Step-by-step explanation:

Harvey rides his bike at an average speed of 12 miles in 1 hour, 24 miles in 2 hours, and so on. Let h be the number of hours he rides and d be distance traveled. Write the equation for the relationship between distance and time in point-slope form.

----

You have three points relating time and distance:

(1,12),(2,24),(3,36)

-----

The slope for your equation would be (24-12)/(2-1) = 12/1 = 12

-------------------------------

The intercept is the distance you would travel in no time; that would be zero.

---------------------------------

The equation is: distance = 12(time)

d = 12t
