Answer:

225 minutes

Explanation:

rate x time x people = 1 job

The rate:


(1 job)/(3poplex5 hours)


(1)/(15) x t x 4 = 1


(4)/(15) t = 1 Multiply both sides by
(15)/(4)


((15)/(4))
(4)/(15) t = 1
((15)/(4))

t =
(15)/(4) hours


(15)/(4) x
(60)/(1) To find out how many minutes. 4 and 60 share a factor of 4. I will use that to work with smaller numbers


(15)/(1) x
(15)/(1) =
(225)/(1) = 225 minutes
