Answer:
the third stage was 480 km long
Explanation:
Stage 1:
Time = 1 hours
Speed = 80km
Stage 2:
Time = 2 hours
Speed = 200km
Stage 3:
Time = 4 hours
Let the Distance at the stage 3 be x
Average speed of the train route = 100 km/h
So
Lets find the speed at stage 1
Speed =
Speed =
Speed 1= 80 km/hr
The speed at stage 2
Speed =
Speed =
Speed 2 = 100 km/hr
The speed at stage 3
Speed =
Speed =
Speed 3 =
we kow that average is ,
x = 480
