Question 848946
Paula walks 8 dogs each day. She walked each of the first 6 dogs for an average of 14 minutes each. For the rest of the dogs she averaged 18 minutes each. What was the average time per walk foe the 8 walks?
--------
average = (total walk time)/(# of dogs) = 
[6*14 + 2*8]/8 = [84+16]/8 = 12.5 minutes
