Question

A factory produces 6 motorcycles in 9 hours. How many hours will it take to produce 16 motorcycles at this rate ?

Answer 1

24 hours

Explanation:

Let m represent motorcycles and h represent hours it takes to make the motorcycles

`6m=9h`

`12m = 18h`

`9 /6=1.5`

`1m = 1.5h`

`1.5 +1.5+1.5+1.5=`

`1.5+1.5=3.0`

`3.0+3.0=6.0`

`=6`

`18+6=24`

`=24h`

Therefore it takes "24 hours" to create 16 motorcycles.

Hope this helps.
