Homework Help: Science Urgent Please help

Posted by Eva on Friday, February 25, 2011 at 9:28am.

(I have no idea how to even approach this question. Can anyone please help me?)

Some people have proposed that the
earth could solve its population problem by shipping people off to space colonies, each containing about 10,000 people. Assuming that we could build such large-scale, self-sustaining space stations, how many people would have to be shipped off each day to provide living spaces for the 82 million people being added to the earth’s population each year? Current space shuttles can handle about 6 to 8 passengers. If this capacity could be increased to 100 passengers per shuttle, how many shuttles would have to be launched per day to offset the 82 million people being added each year?

additional population
= 82,000,000 persons / year
= 82,000,000/365 persons / day
= 224,658 persons / day

With 100 persons per shuttle,
we need
224,658/100
= 2247 shuttle trips / day
