Answer:
45 minutes.
Step-by-step explanation:
Yesterday, he made 6 keychains in 30 minutes.
Hugo wants to make 9 keychains today. We need to find how long will it take him to make the keychains.
6 keychains = 30 minutes
1 keychains = (30/6) minutes
For 9 keychains,
[tex]9\ \text{keychains}=\dfrac{30}{6}\times 9\\\\=45\ \text{minutes}[/tex]
So, to make 9 keychains, it will take 45 minutes.
