Re TY
153mi is the distance traveled in 1hr w/o stopping at the station.
w/o stopping at the station...153mi%2F%281hr%29+=+153mph
avg mph = total distance /total time
x time spent at the station(s)
153mi%2F%281hr+%2B+highlight_green%28x%29+%29+=+72kmph | Cross Multiplying to solve
72 + 72x = 153
72x = 81
x = 81/72 = 9/8 = 1.125hr = 1 1/8 hr,time spent at the stations per hour traveling.
checking: traveling for 2 hrs for ex
306%2F2%281+%2B+1.125%29%29 = 72kmph
