Micheal models an experiment. He places a model car on a tramp that can be adjusted to different heights. Each time the model ca
r travels down the ramp, micheal measures the distance the car travels from the end of the ramp. the graph shows the distance travelled by micheals model car when it leaves the ramp of different heights. A. When the ramp is 2ft high, the model car travels 9ft ft
B. When the ramp is 9ft high, the model car travels 2ft
C. The average speed of the model car is 2ft per sec, when the ramp is 9 ft high.
D. The average speed of the model car is 9ft per second when the ramp is 2ft high
If Buddy makes 15 toys per hour we can use the expression [15x=y] (let x be # of hours worked). If Bubbles makes 12 toys per hour we can use the expression [12x=y]. To find out the number of toys they make together we can just find the total number of toys they make in an hour. (Combine the 2 equations).
