All members of our painting team paint at the same rate. If $8$ members can paint a specific wall in $36$ minutes, then how long would it take $18$ members to paint the same wall, in minutes?
1 answer:
Answer:
16 minutes
Step-by-step explanation:
Time is assumed to be inversely proportional to the number of members painting, so when the number of member is increased by a factor of 18/8, the time is expected to decrease by the factor 8/18 = 4/9.
(4/9)(36 min) = 16 min
18 members can paint the wall in 16 minutes .
