If the velocity of a particle is \(\text{v}\, =\, \text{At}\, +\, \text{Bt}^2\), where A and B are constants, then the distance travelled by it between \(1\,s\) and \(2\,s\) is
(1). \(\displaystyle \frac{3}{2}\,\text{A}\, +\,\frac{7}{3}\,\text{B}\)
(2). \(\displaystyle \frac{\text{A}}{2}\,+\,\frac{\text{B}}{3}\)
(3). \(\displaystyle \frac{3}{2}\,\text{A}\, +\, 4\text{B}\)
(4). \(3\,\text{A}\, +\, 7\,\text{B}\)
