17 cm/min
17 x 60 minutes / 1 hour x 1 meter / 100 cm
you do this because you have to cross multiply to get rid of the measurement since it is 17cm/1min you put 60 minutes at the top to turn it into hours. you then get rid of centimeters by putting 100 cm at the bottom. (Which is how many cm are in 1 meter) You then take 17 x 60 = 1020 You then take 1020/100 and get 10.2. The answer is 10.2 m/h
