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
