Questions & Step-by-Step Solutions
A train moving at 72 km/h overtakes a man walking at 6 km/h in the same direction. How fast does the train appear to be moving to the man?
Step 1: Identify the speed of the train, which is 72 km/h.
Step 2: Identify the speed of the man, which is 6 km/h.
Step 3: Since both the train and the man are moving in the same direction, we need to find the relative speed.
Step 4: To find the relative speed, subtract the speed of the man from the speed of the train: 72 km/h - 6 km/h.
Step 5: Calculate the result of the subtraction, which is 66 km/h.
Step 6: The relative speed of the train to the man is 66 km/h.
Relative Speed – The speed of one object as observed from another moving object, calculated by subtracting the speeds when both are moving in the same direction.
