Velocity of an object fired directly in upward direction is given by ܸ$V\mathit{}=80-32 t\mathit{}$, where $t\mathit{}$ (time) is in seconds. When will the velocity be between $32 \;m/sec$ and $64 \;m/sec$?

- $\left(1, \dfrac{3}{2}\right)$
- $\left(\dfrac{1}{2}, 1\right)$
- $\left(\dfrac{1}{2},\dfrac{3}{2}\right)$
- $\left(1, 3\right)$
