Need help!!!!!!!! PLEASE

Answer 1

80cm

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

Answer 2

1.5 sec divided by 120 = 0.0125 cm

His hight decreases 0.0125 cm each second
