Answer:
Step-by-step explanation:
Work done by Kayla in 1 hour = 1/15
Work done by Jennifer in 1 hour = 1/16
Work done by both Kayla and Jennifer = [tex]\frac{1}{15}+\frac{1}{16}[/tex]
[tex]= \frac{1*16}{15*16}+\frac{1*15}{16*15}\\\\=\frac{16}{240}+\frac{15}{240}\\\\=\frac{31}{240}\\[/tex]
Hours taken by both = 240/31 = 7 23/31 hours
