A particle moves such that its position `x` varies with time according to relation `x=2t-t^(2)`, where `x` is in metres and time in seconds. The incorrect statement about the particle is/are:

A

Velocity of the particle in interval `t=0` to `t=2` sec is in positive `x` direction.

B

Speed of the particle is `1m//s` at `t=3/2s`

C

Distance travelled in the interval `t=0` to `t=2s` is zero

D

Its speed first increases then decreases.
