Question 293457
The time it takes to build a brick wall varies inversely as the number of people working on it. If it takes 3 days for 8 people to build a brick wall, how long will it take 5 people to build the same wall?
:
let d = time for 5 people to complete the job
:
{{{8/5}}} = {{{d/3}}}
5d = 24
d = {{{24/5}}}
d = 4.8 days for 5 to build the wall
