Write down the equation that links distance travelled (sss), constant speed (vvv), and time (ttt).
A high-capacity fiber-optic telecommunications cable laid across the Atlantic Ocean has a length of 5.85 × 106 m. Infrared light signals travel through the glass core of this cable at a constant speed of 1.95 × 108 m/s. Calculate the time taken for a data signal to travel from one end of this ocean cable to the other.
