Plz help me to solve this question
The distance between two stations A & B is 230km.Two motorcyclistr start simultaneously from A&B in opposite directions and the distance between them after 3hours becomes 20km.if the speed of one motorcyclist is 10km,hr less than that of the other,find the speed of the two motorcyclists.

let x be the rate(speed)
TABLE:
R * T = D
M1 x 3 = 3x
M2 x+10 3 = 3(x+10)
solution:
3x+3(x+10)=210 (210, bcoz 23020 or
distance after 3hrs)
3x+3x+30=210
6x=180
x=30kph 
Thank you..

but what is the speed of other cyclist
