Wong's left at 7:00. It took him one and a half hours to check in at the airport. His house is an hour drive from the airport. At what time did Wong leave his house to get to the airport?

I am assuming it is a plane that left at 7:00.

(7:00)-(1.5 hrs check-in)-(1hr drive from house)=4:30

I am home schooled to

600

To find out what time Wong left his house to get to the airport, we need to add up the time it took for him to check in at the airport and the time it takes to drive from his house to the airport.

Wong left at 7:00 and it took him one and a half hours to check in at the airport. Adding one and a half hours to 7:00, we get:

7:00 + 1:30 (one and a half hours) = 8:30

So, Wong finished checking in at the airport at 8:30.

His house is an hour drive from the airport, and we need to calculate what time he left his house to get to the airport. Subtracting one hour from 8:30, we get:

8:30 - 1:00 = 7:30

Therefore, Wong left his house at 7:30 to get to the airport.
