Guys lesson ke end me, me kuchh discuss karna chah rha tha but time khatam ho gya. So usko me yaha bata deta hu A se D ke bich ki distance calculate karni hai? Ab hamare pass train ki speed hai jo (600km/h) hai and us train ko A se D tak jane me 22/3 hours ka time lag rha hai to hum distance calculate kar sakte hai Distance = Speed * Time = 600*(22/3) = 4400 km
sir in first q as we got the speed ratio 3;4 therefor our ans also will be in 3:4 so agar option hota tho direct 75,100 pe tick sahi na
