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.

**HELP HELP HELP MNHS**, Wednesday, January 9, 2013 at 7:52amlet 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
