Step-by-step explanation:
Total duration of time is 6pm to 7am next day.
= 13 hours
Duration for stoppage = 1 hour
Total time taken by train to reach the destination
= 12 hours
Distance between New Delhi to Agra = 220 Km
Speed of the train is
= \frac{distance}{time}=
time
distance
= \frac{220km}{12hour}=
12hour
220km
= \frac{55}{3} kmph=

kmph
And Average speed is
= \frac{total \: distance \: travelled}{total \: time \: taken}=
totaltimetaken
totaldistancetravelled
= \frac{220 \: km}{13 \: hour}=
13hour
220km
= 16 \frac{12}{13} \: kmph=16
