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.
