Answer:
36kmph
Step-by-step explanation:
- Total distance= length of train + Length of platform
- l.e 80+120= 200m but need in Kmph. So 0.2km
- Time = 20 second but need in hours. so 20/(3600) =1/(180)
- Speed = distance / time = 0.2 / 180 = 36kmph

Answer:
10m/s
Step-by-step explanation:
total distance = length of platform + length of train
= 120 + 80
= 200m
speed = distance ÷ time
= 200 ÷ 20
= 10m/s
