let the speed of train that started from Delhi is x km / hour
speed of train that started from Lucknow is x +15
first train covered 8x km in 8 hours
second train covers 8(x+15) in 8 hours
total distance covered = 8x+ 8x+120 = 620
16x = 500
X = 31.25 km
speed of train that starts from Lucknow = 31.25+15= 46.25 km/ hour
