To ride to school, Elaine takes 6 minutes to ride 18 blocks. 

What is her unit rate?  Elaine can ride  3 blocks per minute. Assuming she rides at a constant speed, how long should it take her to go 50 blocks?

We have this proportion....!!!!

 

1 minute / 3 bolcks    =   N minutes  / 50 blocks

 

1/3  = N/50      multiply both sides by  50

 

(50) (1/3) = N  =  16  2/3 min     =  16 min 40 sec

 

 

cool cool cool
