Remember the distance-rate-time f[tex]t = 0.704 hrs[/tex]ormula:
[tex]d=rt[/tex]
Now, if the jet overtakes the plane, then at some point their distances will be the same. This means their rate * time will be equal.
Let's call the rate for the first plane, r1, and the rate for the second plane, r2. If we set time as t, then we can create ourselves a formula. However, we have to add one to the time of the first plane since it leaves one hour earlier. In the end, we should have something like this:
[tex]r_{1}(t+1)= r_{2}t [/tex]
If you plug in the values, you should get:
[tex]t = 0.704h[/tex]
