1. Space explorers set off at a steady speed of 0.8c to a distant planet. Eventually, they turn around and travel with a speed of 0.75c. Measured from Earth, the planet is 1.0 × 10$^{13}$ km (10 trillion km), the time it takes to reach the planet is 482 days, and the return time is 514 days. a. Find the time measured by the space explorers on their way to and from the planet. b. Calculate the total time the space explorers measure their trip. There is no space in the table for this quantity. c. What is the distance the space explorers measure their trip to and from the planet to be?
