In order to calculate the number of hours, "x", that it'll take for Bella to pass Aljan, we need to find the value of "x" that makes both equations equal. Therefore,

$60*x + 20 = 65*x\\65*x - 60*x = 20\\5*x = 20\\x = \frac{20}{5} = 4$

In order to calculate the distance they traveled, we must use this value for "x" in any of the equations, as done below:

$y = 65*4\\y = 260$

Bella will pass Ajjan after 4h and they will have travelled 260 miles.
