Final answer:
To calculate the distance an airplane travels in meters, you convert the flight time to a single unit, either hours or minutes, and then multiply the distance in kilometers by the conversion factor of 1000 meters per kilometer.
Step-by-step explanation:
The question involves calculating the distance an airplane travels in meters when given a distance in kilometers and time in hours and minutes. To find the distance in meters, you need to first convert the time from hours and minutes to just hours or just minutes, and then use a conversion factor to change kilometers to meters.
Since 1 hour is 60 minutes, 1 hour 20 minutes is the same as 80 minutes. The jet travels 1200 km in 80 minutes, which means in terms of hours, the time is ⅔ hours (since 80 minutes is ⅔ of an hour).
To convert kilometers to meters, we use the conversion factor that 1 kilometer equals 1000 meters. Therefore, to calculate the total distance traveled by the jet in meters:
Distance in meters = 1200 km * 1000 meters/km
This will give you the total distance in meters that the jet travels.
