Answer:
Please check the explanation.
Step-by-step explanation:
As an airplane travels 780 miles in 4 hours.
We need to determine the table and graph to show the mileage for 2,8 and 12 hours.
as
The airplane covers the distance in 4 hours: 780 miles
so
The airplane covers miles in 1 hour will be: 780/4 = 195 miles
Hence, the table can be calculated as:
Hours Distance Mileage in Miles
[tex]2[/tex] [tex]2\times195\:=\:390[/tex] miles
[tex]8[/tex] [tex]8\times195 = 1560[/tex] miles
[tex]12[/tex] [tex]12\times195 = 2340[/tex] miles
It is clear from the table that it is a direct variation as the constant is 195 miles per hour.
Please check the attached graph. The graph clearly indicates a direct variation.
