You can put this solution on YOUR website!
slower cyclist is x kph
faster cyclist is x+4 kph
in 1.5 hours, their distance is 39 km
39 km/1.5 hours is 26 kph
x+ (x+4) =26
2x +4=26
2x=22
x=11
x=4=15
They are traveling apart at 26 kph; in 1.5 hours they will be 39 km apart.
The slower is traveling at 11kph; the faster at 15 kph.
