(? i'm getting really confused on kevin wants to make a mixture that is 50% lemon juice and 50% lime juice. how much 100% lemon juice should he add to a juice mixture that is 40% lemon juice and 60% lime juice to make 6 gallons of the 50% lemon/50% lime juice mixture? 0.5 gallon 1 gallon 2 gallons 2.5 gallons

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?
