195- According to the figure below, two radio stations A and B are located $80\,\text{km}$ apart and each sends a signal. Point P is located $60\,\text{km}$ from A. These two signals reach point P with what time difference? $\left(c = 3\times10^{8}\,\dfrac{\text{m}}{\text{s}}\right)$ [Figure: Point P above, points A and B on a horizontal line, with P located 60 km from A and A and B separated by 80 km] (1) $\dfrac{4}{3}\times10^{-4}$ (2) $\dfrac{4}{3}\times10^{-7}$ (3) $\dfrac{2}{3}\times10^{-4}$ (4) $\dfrac{2}{3}\times10^{-7}$
