Hey,
Thanks for asking this question.
Here is your answer-
Suppose speed of 1st train is x km/hour.
Speed of second train,y = distance/speed
=> y = 400/5 km/h
=> y = 80 km/h
According to the question,
x/y = 7/8
=> x/80 = 7/8
=> 8x = 560
=> x = 70 km/h
●So the speed of first train is 70 km/hour.
●●● Hope my answer helped.
