WHO EVER GET IT RIGHT WILL GET BRAINLY!!! 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?
