Kindly check attached picture for number line.

Explanation:

Total time Allen would love to complete race is less than 5.5 hours

Time elapsed = 3 hours

Inequality representing the problem above :

3 + t < 5.5

Where t will mean the time left.

Solving for t

t < 5.5 - 3

t < 2.5

Time left is < 2.5 hours.
