Sound waves can travel much faster from one point to another. And nobody has to be on the other end of the measuring stick. Sound waves are far more accurate for measuring these vast distances.

Velocity=Distance/time
Distance=Velocity*time
They divide the distance by 2 (since the sonar wave has to return as well.)
They make thousands of these measurements to make a map of the ocean floor based on these distances.

What is sonar which research vessel first used sonar to map the mid-Atlantic ridge?
the Challenger
What did scientist use to map the ocean floor?
sonar - by bouncing sound signals off the bottom of the ocean, they were able to map the depth of the ocean. Deep sea diving would take too long. Satellites were not in orbit until the 1970's and submarines were not necessary since sonar could be done from the surface on a boat.
