Answer 1

• As Rajdhani Express leaves Patna at 2040 hours and Reaches Lucknow at 2400 hours, the time took to reach Patna to Lucknow is 2400 hours-2040 hours=3 Hours 20 Mins=200 mins.
• As it stops for 30 mins in Lucknow So it left Lucknow at 0030 hours.  
• So time taken to Reach Delhi to Lucknow is =0600 Hours-0030 Hours= 5 hours 30 mins=330 mins
• So the total time travelled by the train is= 200 mins+ 330 mins=530 mins.
• Speed= Distance/Time=1320/530 km per min= 1320/530*60 km per hour=149.43 km / hour
