If you walk at 1 km/h down the aisle of a train that moves at 60 km/h, what is your speed relative to the ground?

Solution 1RQ Step 1: This is the case of a person walking with 1 km/hr speed inside a 60 km/hr speed train. So, for an external observer at ground, the speed of the train will be 60 km/hr. The speed of the man walking inside the train is given as, v ‘ = 1 km /hr Therefore, the exact speed of the person inside the train relative to the observer at ground will be, V = v + v ‘ Where, v - velocity of the train v ‘ - velocity of the person walking inside the train Therefore, V = 60 km/hr + 1 km / hr = 61 km /hr Conclusion: So, the speed of the person relative to the ground will be 61 km/hr.
