OK!
a) Dead Reconing. Or so it says here.
• Dead reckoning requires determination of direction and rate of travel. With a known starting location and a series of distance and direction data stored in a log and marked on a chart a mariner could safely arrive at the intended destination.
• Rate of travel requires measurement of time and velocity.
• To measure velocity the “log and line” was heaved over the side.
