It takes 4 people 20 minutes to load 10 items on to a truck. How many items can 8 people load in one hour?

Answer 1

4 do 10 in 20

8 do 20 in 20

8 do 3(20) in 3(20)

8 people can do 60 in 1 hour or 60 minutes

8 people do as many item as there are minutes

8 do 30 in 30 minutes

8 do 50 in 50 minutes

8 do n items in n minutes

assuming the same constant rate of speed

4 do 10 in 20

1 does 10/4 in 20

1 does 2.5 in 20

1 does 2.5(3) = 7.5 in 60

4 do 7.5(4) = 30 in 60

8 do 7.5(8)= 60 in 60

n do 7.5n in 60 minutes
