for the 15 th one ..
u should always take the speed which is less ...first and then subtract it with the next equation. e.g..1500/x minus 1500/ x + 100 = 1/2 hour ( 30min )

khushigandhi2443: Ohhk....so we will solve these type of questions (Q15) like that only?
akul7791: Ya...always take the speed which is less first and then only subtract...u will get the answer ...but always keep in hrs only
akul7791: e.g. 1500/x is less than 1500/x+100 because it's x+100
khushigandhi2443: Ohhk.
khushigandhi2443: Thank you so much
