Step-by-step explanation:
speed-60; time -30 sec
length of train = speed/time
= 60/30
= 20m
Answer:
500 meters
Step-by-step explanation:
Converting the train’s speed
Train’s speed = 60 km/h
Train’s speed = 60,000 m / 3,600 s
Train’s speed = 50/3 m/s
Solving for the distance traveled in 30 seconds
distance traveled = Train’s speed * elapsed time
distance traveled = 50/3 m/s * 30 s
distance traveled = (1500 / 3) m
distance traveled = 500 m
Solving for the length of the train
Length of the train = distance traveled
Length of the train = 500 meters
