A train started from station 'A' and proceeded towards station 'B' at a speed of 48 Km/hr. Forty-five minutes later another train started from station 'B' and proceeded towards station 'A' at 50 Km/hr. If the distance between the two stations is 232 Km, at what distance from station 'A' will the trains meet?
a)

Dear Student

They will meet when sum of the distance covered by them is 232 km

suppose they meet after t hr of departure time at A

then travelling time of B will be t-3/4 hrs

D_A=48t

D_B=50(t-3/4)

D_A +D_B=  48t + 50(t-3/4)=232

solving we get t=11/4 hrs

distance from A= 48x11/4=132 km

All the best.
