Bunny hill ski resort charges $35 for ski rental and $10 an hour to ski. black diamond ski resort charges $40 for ski rental and $5 an hour to ski. create an equation to determine at what point the cost of both ski slopes is the same.

Me with this assignment ! i only partially understand, so explain. also it's a work sample. at the championship bike race, steve and paula were fighting for first place. steve was 175 feet ahead of paula and had only 300 feet left to go. he was very tired and was going only 9 feet per second. paula was desperate to catch up and was going 15 feet per second. who won the bike race and by how far did she/he win?
