A runner travels 2 miles in the first 10 minutes and 3 miles in the next 20 minutes. What is the average speed of the runner in miles per hour? Using the graph, calculate the average speed. What is the average speed of a helicopter that flies 50 km in 20 minutes and then 30 km in 10 minutes? What is the average speed of a lizard that runs 100 meters in 40 seconds and then runs an additional 50 meters in 20 seconds?

it would be the percentage of food eaten by the flock

i remember doing this lab

for example, no new evidence will demonstrate that the earth does not orbit around the sun (heliocentric theory), or that living things are not made of cells (cell theory), that matter is not composed of atoms, or that the surface of the earth is not divided into solid plates that have moved over geological timescales .

the answer is c because it is most logical.
