John leaves point A to travel 360klm and Joanne leaves point A 40 mins later and her cars speed is 18klm per hour faster than John's but they both arrive at the same time. What is their respective speeds?

The both travel the same distance.

distance=rate(time)

distanceJohn= rateJohn*timejohn
distanceJoanne=(rateJOhn+18)(timejohn-40/60)

both distances are the same, 360km.
