A car moves along a straight horizontal road. The graph illustrates how the car’s velocity $v$ changes with time $t$ during $6.0\,\text{s}$ of its journey. The car’s brakes are applied during the interval from $t = 1.0\,\text{s}$ to $t = 4.0\,\text{s}$. How far is the car moved in the time when the brakes are applied?
- A$21\,\text{m}$
- B$45\,\text{m}$
- C$67\,\text{m}$
- D$83\,\text{m}$
