If a train traveled at 50 meters within 120 seconds, what is its speed?
1 answer:
Answer:
v = 0.416 m/s
Step-by-step explanation:
Give that,
Distance covered by a train, d = 50 m
Time taken, t = 120 s
We need to find the speed of a train. The formula for speed of an object is equal to the total distance covered divided by total time taken. It can be given by :
So, the speed of a train is 0.416 m/s.
