Explanation:
Detailed explanation-1: -As given above, the velocity of the train is 120miles per hour. It means in 1hour the train travels 120miles. So in 3.5 hours the train travels= 120×3.5=420 miles. So the distance between two cities is= 420miles.
Detailed explanation-2: -Answer: Speed = Distance divided by Time. So, speed = 75 miles divided by 2.5 hours = 75 / 2.5 = 30 miles per hour. Velocity is speed and direction, so the velocity is 30 mph Northbound.
Detailed explanation-3: -And that is 50 kmph. And that’s the answer. Hope it helps.
