Question

if 2/5 of length of a pole is embedded in mud ,3/10 in water and 3 metres above the surface of water ,find the length of the pole

Answer 1

to get the answer we need to add all of the lengths in water, in mud, and above the water.
.
. .length above the ground=3m
length in water =3/10m
length embedded in the mud=2/5m
.
. .total length of pole =3+2/5+3/10
=>3+4/10+3/10
=>3+7/10
=>37/10
=>3.7m
