Answer:

The speeds are 66.67 km/h and 133.33 km/h.

Step-by-step explanation:

Train 1

speed = s

distance covered = d

time of travel = t = 1.5

Train 2

speed = 2s

distance covered = 300 - d

time of travel = t = 1.5

speed = distance/time

distance = speed × time

Train 1

distance = speed × time

d = st

d = 1.5s

Train 2

distance = speed × time

300 - d = 2st

300 - d = 2s(1.5)

300 - d = 3s

300 - 1.5s = 3s

300 = 4.5s

s = 66.67

2s = 2 × 66.67 =133.33

The speeds are 66.67 km/h and 133.33 km/h.
