Question: A train takes 10 seconds to cross a bridge that is 300 meters long. If the train is 200 meters long, what is the speed of the train?

Options:

Correct Answer: 30 m/s

Solution:

Total distance = Length of train + Length of bridge = 200 + 300 = 500 m. Speed = Distance / Time = 500 m / 10 s = 50 m/s.

A train takes 10 seconds to cross a bridge that is 300 meters long. If the train is 200 meters long, what is the speed of the train?

A train takes 10 seconds to cross a bridge that is 300 meters long. If the train is 200 meters long, what is the speed of the train?

Step 1: Identify the length of the train, which is 200 meters.
Step 2: Identify the length of the bridge, which is 300 meters.
Step 3: Calculate the total distance the train travels while crossing the bridge. This is the length of the train plus the length of the bridge: 200 meters + 300 meters = 500 meters.
Step 4: Identify the time it takes for the train to cross the bridge, which is 10 seconds.
Step 5: Use the formula for speed, which is Speed = Distance / Time. Here, the distance is 500 meters and the time is 10 seconds.
Step 6: Calculate the speed: 500 meters / 10 seconds = 50 meters per second.

Distance, Speed, and Time – Understanding the relationship between distance, speed, and time is crucial for solving problems involving motion.
Relative Motion – Recognizing that the total distance to be covered includes both the length of the train and the length of the bridge.
