It is negative. It is zero. It can be positive, negative, or zero. It isn't zero.

Explanation / Answer

in a one dimentioanl motion

the speed being calculated based on the distance travelled by the time taken to travell that distance

distance being a scalar doesn't depend upon the initial and final positions

the path which it covers is also considered i.e distance

going to the problem

the body returns to its original position

covered the distance 2 tooo and fro so the speed is distance travelled by time

as the distance covered is always positive and direction independent the

speed of the body is positive
