That should be the Grasslands ?
        
             
        
        
        
First change km/ s into m/s, then use the formula 
Lambda = velocity/ frequency
        
             
        
        
        
LiCl, because lithium (Li) has one positively charged ion (1+), and
chloride (Cl) has one negatively charged ion (1-), so they
cancel each other out.
        
                    
             
        
        
        
Set up a proportion
1 mile/1.6 km = 20,000miles/x
Cross Multiply
x = (20,000) * (1.6)
x = 32,000 kilometers
