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.

• Math -

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 230-20 or
distance after 3hrs)
3x+3x+30=210
6x=180
x=30kph
