Answer:
1.6 above water
Step-by-step explanation:
Total length of the pipe = length below the water + length above the water
We know the total length of the pipe =3.1 and the length below the water is 1.5 m
3.1 = 1.5 + length above the water
Subtract 1.5 from each side
3.1 -1.5 = 1.5 -1.5 + length above water
1.6 = length above water
