194 From two places, 60 km apart A andB start towards each other at thesame time and meet each other af-ter 6 hours. If A travelled with ofhis speed and B travelled withdouble of his speed they wouldhave met after 5 hours. The speedof A is

Answer»

A to B 60kmLet the speed of A= x kmph and that of B = y kmph;

According to the question;X*6+y*6 = 60Or, x+y = 10 --------- (i)

And,

{(2x/3)*5}+(2y*5) = 60

Or, 10x+30y = 180;

Or, x+3y = 18; ---------- (ii)

From equation (i)*3 - (ii)

3x+3y-x-3y = 30-18Or, 2x = 12

Hence, x = 6 kmph
