Answer:
Time taken by the second train to cover the total distance of the first train = 5 hours.
Speed of the second train = 70 km/h
v = s/t
70 = s/5
s = 70 x 5
Total distance = 350km
Time taken by the first train to cover 350km = 7 hours.
v = s/t
v = 350/7
v = 50km/h.
Speed of the first train is 50km/h
