The distance x of a runner from a fixed point is measured in

The distance x of a runner from a fixed point is measured (in meters) at intervals of half a second. The data obtained is Use Forward difference central difference backward difference to approximate the runner\'s velocity at time t = 0.5, and t = 1.5s. Find the velocity approximation error in each method. (Give your answers to 3 decimal places) Calculate the runner\'s velocity and the truncation error using central difference at time t = 0.75s.
