Spacecraft in 1997, the Pathfinder spacecraft landed on Mars. It contained a robotic vehicle named Sojourner that could roam up to 500 meters from the lander. The distance d (in meters) that Sojourner could travel in t hours is given by. How long would it take Sojourner to reach its maximum distance from the lander?
1. Copy and complete the table using the given equation
