               SPEED     TIME         DISTANCE

jimmy            24        5             d
 
maria            r                       d

difference                1


Maria's speed r is to be found. Maria's time is to be found.
The distance they each traveled, kilometers.


               SPEED     TIME         DISTANCE

jimmy            24        5            120
 
maria            r        6             120

difference                1

Since the time difference had to be 1 hour as given, Maria going slower, had to travel for MORE time; 6 hours.

Her average speed:


----------kilometers per hour, Maria

I took Maria 6 hours to travel the same distance Jimmy traveled in 5 hours.

That means Maria's speed was 5/6 of Jimmy's speed.

(5/6)*24 = 20

Maria's speed was 20 km/h.
