Answer:

  • Annie- 17 hours, Brian- 3 hours

Step-by-step explanation:

Let the number of hours Annie travelled be a, and same of Brian be b

<u>Then we have</u>

  • a + b = 20
  • a = 5b + 2

<u>Substituting a in the first equation</u>

  • 5b + 2 + b = 20
  • 6b = 20 - 2
  • 6b = 18
  • b = 3

<u>Then finding a</u>

  • a = 20 - 3 = 17

<u>So the answer is:</u>

  • Annie- 17 hours, Brian- 3 hours
