Answer:
16 hours
Step-by-step explanation:
let t be time, n the number of computers and w the number of workers, then
t = 
← k is the constant of variation
To find k use the condition n = 30, w = 6 and t = 10 , then
10 = 
( multiply both sides by 6 )
60 = 30k ( divide both sides by 30 )
2 = k
t = 
← equation of variation
When w = 5 and n = 40 , then
t = 
= 
= 16 hours
20*1.95 =39 girls
26girls/39girls =0.667
0.667*100 = 66.67%
23 miles per hour is 2024 feet per minute
Alan goes at 1600 and Barry goes at 2024
So, Barry goes faster
Hope this helps!
They are independent because they do not rely on each other.
