If 3 workers can assemble 2 bookcases in 45 minutes, how long would it take 5 workers to assemble the bookcases?

27

Step-by-step explanation:

r=rate of 1 worker

t=time

3 x r x 45 = 5 x r x t

t= 3 x 45 / 5

t= 3 x 9

t= 27

90

Step-by-step explanation:

In the ratio 2:3,2 is the original hence 60 is also the original and your are supposed to increase it.

Solution

Because 2 and 60 are both original we say

if 2=60

what about3

to have 3x60÷2
