Answer:
The boys can build 30 snowmen in an hour
Step-by-step explanation:
Extracting the key information from the question:-
*** 3 boys can build 4 snowmen I 24 minutes.
*** 9 boys are to build snowmen.
*** How many snowmen can be built by the 9 boys in an hour.
Firstly, since 3 boys can build four (4) snowmen in 24 minutes, we need to convert one hour to minutes.
60 minutes = 1 hour.
Now, since three boys can build four (4) snowmen in twenty four (24) minutes, we need to know or find out how many snowmen that none boys can build in the same time if they all work at the same rate as the three boys.
3 boys ------------- 4 snowmen (24minutes)
9 boys -------------- ? snowmen (24 minutes)
= 9/3 × 4
= 36/3
= 12 snowmen (24 minutes).
Now, 9 boys can build 12 snowmen in 24 minutes. All we now need to do is to determine or figure out how many snowmen that the nine boys can build within an hour of work (60 minutes).
Since nine boys can build 12 snowmen in 24 minutes, the number of snowmen that they can build in an hour (60 minutes) is:
(9 boys) 24 mins ------- 12 snowmen
(9boys) 60 mins --------- ? snowmen
= 60/24 × 12
= 720/24
= 30 snowmen
Therefore, 9 boys can build 30 snowmen in one hour if they all build at the same rate as the initial three boys.
