Answer 1

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
