Problem: As of the census of 2000, 750,097 people, 286,098 households, and 197,693 families resided in the county. The population density was 1,553 people per square mile (599/km). The 297,434 housing units averaged 238 units/km (616 units/sq mi). The Race (United States Census) of the county was 86.46% White, 7.46% Black or African American, 0.11% Native American, 4.02% Asian, 0.03% Pacific Islander, 0.75% from other races, and 1.16% from two or more races. About 2.04% of the population were Hispanic or Latino of any race, 17.5% were of German people, 16.7% Irish people, 14.3% Italian people, 6.5% English people, and 5.0% Polish people ancestry according to 2000 United States Census. Around 90.5% spoke English language, 2.0% Spanish language, 1.1% korean language, and 1.0% Italian language as their first language. Historically, much of western Montgomery County is part of the Pennsylvania Dutch Country, with a great many descendants of German language-speaking settlers from the 18th century.

Problem: In 2010, there were 340,523 family households, out of which 33.5% had children under the age of 18 living with them, 60.0% were Marriage living together, 11.7% had a female householder with no husband present, and 24.1% were non-families. 20.1% of all households were made up of individuals and 15.1% had someone living alone who was 65 years of age or older. The average household size was 2.94 and the average family size was 3.38. The population was 23.3% under the age of 18, and 18.7% who were 62 years of age or older. The median age was 41.1 years. For every 100 females, there were 93.7 males. For every 100 females age 18 and over, there were 90.4 males.

Problem: The brightest star in the constellation, Gamma Velorum, is a complex multiple star system. The brighter component, known as Gamma2 Velorum or Suhail, shines as a blue-white star of apparent magnitude 1.83. It is a spectroscopic binary made up of two very hot blue stars orbiting each other every 78.5 days and separated by somewhere between 0.8 and 1.6 Astronomical Units (AU). The brighter component is a hot blue main-sequence star of spectral type O7.5 and is around 280,000 times as luminous, is around 30 times as massive and is 17 times the diameter of our Sun with a surface temperature of 35,000 K. The second component is an extremely rare example of hot star known as a WolfRayet star, and is the brightest example in the sky. It has a surface temperature of 57,000 and is around 170,000 times as luminous as our sun, though it radiates most of its energy in the ultraviolet spectrum. Gamma1 is a blue-white star of spectral type B2III and apparent magnitude 4.3. The two pairs are separated by 41 arcseconds, easily separable in binoculars. Parallax measurements give a distance of 1,116 light-years, meaning that they are at least 12,000 AU apart. Further afield are 7.3-magnitude Gamma Velorum C and 9.4-magnitude Gamma Velorum D, lying 62 and 93 arcseconds southsoutheast from Gamma2.
Answer this question based on the article: How many more times as massive is Gamma Velorum than it is wide?
A:
