PLEASE HELP I WILL AWARD BRANLIEST - 4 kitchen assistants can prepare 10kg of vegetables in 45 minutes. How long would it take 15 assistants to prepare the same amount?

Answer:
12 minutes
Step-by-step explanation:
We need to find the total amount of work time to do the job
4 * 45 = 180 work minutes
We now get 15 assistants, so take the work time and divide by the assistants
180 / 15 =12
They will need 12 minutes
