A cyclist traveled 20 kilometers per hour faster than an in-line skater. In the time it took the cyclist to travel 80 kilometers,
the skater had gone 30 kilometers. Find the speed of the skater.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 = ,

80s = 30(s+20),

80s = 30s + 600,

50s = 600,

s = 12 km/h is the skater speed.

Answer. Skater speed is 12 km/h,  cyclist speed is 12+20 = 32 km/h.
