drive more than 40 miles daily, and 1/6

of the graduate students drive more than 40 miles daily. If there are twice

as many undergraduate students as there are graduate students, then what fraction of the commuters drive more

than 40 miles daily?

**Reiny**, Wednesday, August 11, 2010 at 9:15pmnumber of grad students = x

number of undergrads = 2x

grads more than 40 miles = x/6

undergrads over 40 miles = 2x/10

total over 40 miles = 11x/30

undergrads commuting = 2x/4

grads commuting = x/3

total commuting = 5x/6

fraction of commuters over 40 miles = (11x/30)÷(5x/6) = 1/25
