WATER DEPTH An echo sounder is a device used to determine the depth of water
by measuring the time it takes a sound produced just below the water surface to
return, or echo, from the bottom of the body of water. The accuracy of an echo
sounder is the positive difference between the depth of water reading on the echo
sounder r and the actual depth of water w. Write two absolute value expressions
equivalent to the accuracy of an echo sounder.
