The cheerleаders аt Silver Springs High Schооl аre making and selling Christmas wreaths tо earn money for their trip to Orlando. They currently have orders for 60 wreaths. The girls divide up into groups to construct the wreaths and after making one wreath, Samantha estimates it will take her group 16 hours to make all the wreaths if they work alone. Aleysia’s group estimates that they can make all the wreaths in 24 hours if they work alone. How long will it take the two groups, working together, to make all 60 wreaths?
