Thank you for the opportunity to help you with your question! the solution is as such:

let the initial speed be x miles per hour.

total distance = 12000 miles.

so time t1= 12000/ x hours


now.

new speed = (x+600) miles / hr

total distance = 12000 miles.

so time t2= 12000/ (x+600) hours

we know 

t2 -t1 = 1hr

so.

 [12000/ x]  - 12000/ (x+600) = 1

on solving for x we get x= 2400 miles er hour

so the cruising speed was 2400 miles per hour.
