Solve the problem. Round to the nearest tenth unless indicated otherwise.Wind resistance or atmospheric drag tends to slow down moving objects. Atmospheric drag varies jointly as an object's surface area A and velocity v. If a car traveling at a speed of 40 mph with a surface area of 34 ft2 experiences a drag of 231.2 N (Newtons), how fast must a car with 39 ft2 of surface area travel in order to experience a drag force of 483.99 N?
A. 73 mph
B. 78 mph
C. 70 mph
D. 75 mph
