A biology teacher drives from Naperville over the Cleveland to visit her sister. During the trip there, she travels the first half of the time at 60 km/hr and the second half the time at 95 km/hr. When she comes back, she drives the first half the distance at 60 km/hr and the second half of the distance at 95 km/hr.
Required:
a. What is her average speed going over to Cleveland?
b. What is her average speed coming back from Cleveland?
c. What is his average speed during the entire trip?
d. What is his average velocity during the entire trip?

The ratio of lift to drag l/d for a wing or airfoil is an important aerodynamic parameter, indeed, it is a direct measure of the aerodynamic efficiency of the wing. if a wing is pitched through a range of angle of attack, l/d first increases, then goes through a maximum, and then decreases. consider an infinite wing with an naca 2412 airfoil. estimate the maximum value of l/d. assume that the reynolds number is 9x10^6.
