Answer:
24 hours
Step-by-step explanation:
Let m represent motorcycles and h represent hours it takes to make the motorcycles
[tex]6m=9h[/tex]
[tex]12m = 18h[/tex]
[tex]9 \div6=1.5[/tex]
[tex]1m = 1.5h[/tex]
[tex]1.5 +1.5+1.5+1.5=[/tex]
[tex]1.5+1.5=3.0[/tex]
[tex]3.0+3.0=6.0[/tex]
[tex]=6[/tex]
[tex]18+6=24[/tex]
[tex]=24h[/tex]
Therefore it takes "24 hours" to create 16 motorcycles.
Hope this helps.
