Questions & Step-by-Step Solutions
A train is moving at 90 km/h and a bird flies at 45 km/h in the opposite direction. What is the speed of the bird relative to the train?
Step 1: Identify the speed of the train, which is 90 km/h.
Step 2: Identify the speed of the bird, which is 45 km/h.
Step 3: Since the bird is flying in the opposite direction to the train, we need to add the speeds together.
Step 4: Calculate the relative speed by adding the speed of the train and the speed of the bird: 90 km/h + 45 km/h.
Step 5: The result of the addition is 135 km/h, which is the speed of the bird relative to the train.
Relative Speed – Relative speed is the speed of one object as observed from another object, calculated by adding their speeds when they are moving towards each other.
