Answer:
d = 24/7 days
Step-by-step explanation:
Hi,
Given that Kaitlyn can build a shed in 6 days,
In 1 day, kaitlyn can build 1/6 th of shed.
Given that Mark can build a shed in 8 days,
In 1 day, kaitlyn can build 1/8 th of shed
If Kaitlyn and Mark work together,
In 1 day they can build (1/6 + 1/8) th = 7/24 th of a shed
To finish the entire shed, they require 1/(7/24) days
= 24/7 days
If Kaitlyn takes x days to build a shed and Mark takes y days to build
the same shed, the number of days they would take working
together is given by d = xy/(x + y)
Hope, it helps !
