Answer: 10 years
Step-by-step explanation:
Let d represent Daniel's age.
From the information given, Two times Megan's age is the same as four times Daniel's age. Thus,
2 x Megan's age = 4d
Daniel is five years old. This means that
2 x Megan's age = 4 x 5 = 20
Megan's age = 20/2 = 10
Megan is 10 years
