Janet can mow a lawn that measures 600 square decimeters is 1 1/2 hours.at this rate,how many minutes would it take her to mow a lawn that measures 600square meters?.

Sagot :

Convert 600m² to dm².
600m² = 6000dm²

600dm
² : 90min. = 6000dm² : X       

   6000

x     90  
540000
 

540000 = 900
 
  600
 

X = 900 minutes  

Checking:
  600dm² : 90min. = 6000dm² : 900min.     
   
    6000
    x  90  
  540000
        
  
     900

  x 600
 540000
