Hi!
We know that it flies 1000 kilometers per hour. It's traveling at a constant speed, so that means that it will
always
be traveling at that speed.
To know how far it flies in 3 1/2 hours, we multiply 1000 by 3 1/2
[tex]1000 * 3\frac{1}{2}[/tex]
[tex]3500[/tex]
Therefore, it flies 3500 kilometers in 3 1/2 hours.
