A deep-space exploration probe, Aethelgard, is orbiting a distant exoplanet. It transmits high-frequency telemetry data back to a tracking station on Earth via a laser beam.
The distance between the probe and the tracking station is 1.35×1011 km1.35 \times 10^{11}\,\text{km}1.35×1011km.
The speed of the laser signal is 3.0×108 m/s3.0 \times 10^8\,\text{m/s}3.0×108m/s.
Calculate the time taken, in seconds, for the telemetry data to reach the tracking station. Give your answer in standard form.
