Answer:
80cm
Step-by-step explanation:
120cm = 1.5
Make it a whole number
120cm = 1.5
120cm = 3
Since you multiplied 1.5 by 2 to get to 3, Do the same to the other side
120 = 3
240 = 3
Now it's equivalent
Then you have to get the 3 seconds down to 1 so you divide both sides by 3
240/3 = 3/3
80 = 1
80 cm per second
