2. Sumin runs 50 meters from her house to the park down the street. She then keeps running in the same direction to her friend's house 150 meters from the park. She then turns around and goes back to the
park. What is Sumin's average velocity during her run if it takes her 2 minutes to complete?
a. 25 m/s
b. 2.92 m/s
C. 3.33 m/s
d. 0.417 m/s

Suppose you run 2 miles from your house to a friends house at a speed of 7 mi/hr. When the time comes to return home, you are tired and walk the same 2 miles at 3 mi/hr.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods

the temperature in kelvin of 2.0 dm3 of an ideal gas is doubled and its pressure is increased by a factor of four. what is the final volume of the gas
