- 150 km
Let after time t hrs both the trains meet, then
Distance travelled by train leaving at 10 am with speed 60 kmph in t hrs= Distance travelled by train leaving at 10:30 am with speed 75 kmph in t -½ hrs.
=> 60t = 75(t - ½)
=> 120t= 75(2t -1)
=> 30t= 75 or t=15/6 =2 ½
So calculating distance travelled by either first or second train 60t or 75(t- ½) = 60* 2½= 150 km. - 8 years agoHelpfull: Yes(1) No(2)
