Answer:
c =3.9375 hours
Step-by-step explanation:
The formula to determine time to finish the job together is
1/a + 1/b = 1/c
Where a and b are the times to complete the job separately and c is the time to complete the job when working together
1/7 + 1/9 = 1/c
Multiply by 63c to get rid of the fractions
63c*(1/7 + 1/9) = 1/c *63c
9c + 7c = 63
Combine like terms
16c = 63
Divide each side by 16
16c/16 = 63/16
c =3.9375 hours
