Duana Worthem's 40 years of experience in the automotive industry, combined with her education and location, suggest a relatively low hourly rate. Considering the average salary for a retired executive in the automotive industry, I estimated her hourly rate to be around $45, which is lower than the national average for executives with similar experience. This rate is also lower than what professionals with similar skills and experience in other industries might charge, highlighting the specific context of the automotive industry and Duana's role as a retired executive.
