A family took a trip in a car traveling East from Greensboro to Wilmington, NC. Use the Graph to answer the questions below. 1: Calculate the average speed of the trip.

2: What was the average velocity of the car?

Note: Please don't put weird stuff or completely off-topic stuff, I really need help for this homework! Thanks!

Consider a u-tube whose arms are open to the atmosphere. now equal volumes of water and light oil (ρ = 49.3 lbm/ft3) are poured from different arms. a person blows from the oil side of the u-tube until the contact surface of the two fluids moves to the bottom of the u-tube, and therefore, the liquid levels in the two arms are the same. if the fluid height in each arm is 30 in, determine the gage pressure exerted by the person on the oil by blowing.
