Given Information: We are given that Benji's flight from Chicago to San Jose took $4.5$ hours and that this flight was $0.5$ hour longer than his return flight from San Jose to Chicago. To find the duration of the return flight, we need to subtract the additional time from the duration of the outgoing flight. $\newline$ $4.5$ hours - $0.5$ hour
Simplify the expression: Subtract $0.5$ from $4.5$ . $\newline$ $4.5$ hours - $0.5$ hour = $4$ hours $\newline$ Duration of the return flight: $4$ hours
