Answer 1

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

Then we have

• a + b = 20
• a = 5b + 2

Substituting a in the first equation

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

Then finding a

• a = 20 - 3 = 17

So the answer is:

• Annie- 17 hours, Brian- 3 hours
