more to cover the distance by Car than Train. Find
average speed of Journey.​

Answer 1

Answer:

x=31.25

Step-by-step explanation:

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
