choose 1 answer:
a 5
b 4.5
c 4
d 3.5

Explanation:

Step1: Define return flight time

Let $t$ = return flight duration (hours)

Step2: Set up equation

The Chicago to San Jose flight is 0.5 hours longer than the return flight, so:
$t + 0.5 = 4.5$

Step3: Solve for $t$

Subtract 0.5 from both sides:
$t = 4.5 - 0.5$
