Well 3 bulbs every 2 minutes means 1 bulbs every 2/3 of a minute right? So 57*2/3 minutes =?

You can do this as a ratio

If Rosa can plant
3 bulbs
------ 
2 minutes

the questions wants to know
57 bulbs
-------
x minutes

so

3 bulbs        57 bulbs
------ =   ---------
2 minutes       x min


you can cross multiply and solve for x
