since they are leaving each other perpendicularly, you need to use a right triangle.
The lapse of time is equal so, t is the same for both directions. a=24t for one leg of your triangle and b=32t for the other. c=d is the hyponenuse.
Replace a^{2}+b^{2}=c^{2}(pathagoreum theorem) with the given info above.
(24t)^{2} + (32t)^{2} = d^{2}
solve for d by taking the square root of both sides.
d = sqrt((24t)^{2} + (32t)^{2})
hope this helps!
