I need help pls! A group of hikers park their car at a trail head and hike into the forest to a campsite. The next morning, they head out on a hike from their campsite walking at a steady rate. The graph shows their distance in miles, d, from the car on the day of their hike after h hours. How far is the campsite from their car? Write an equation that describes the relationship between d and h. After how many hours will the hikers be 16 miles from their car?
