graph shows how far Erin was from her house
after each minute of her trip.

first 4 minutes of her trip. What was this
speed? 30
Distance (m)
800 +
b. What was Erin's average speed for
the whole trip?
0 1
2
8 9 10
3 4 5 6 7
Time (min.)
c. What was her average velocity?

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !
