Q. Two freight trains leave the station in Allenville at the same time. The first train is headed due south at a speed of kilometers per hour. In comparison, the second train is going due north at kilometers per hour. In how long will the trains be kilometers apart?If necessary, round your answer to the nearest minute.____ hours and ____ minutes
- Calculate Combined Speed: Calculate the combined speed of the two trains moving in opposite directions.Speed of first train: kilometers per hourSpeed of second train: kilometers per hourCombined speed = Speed of first train + Speed of second trainCombined speed = Combined speed = kilometers per hour
- Calculate Time Apart: Calculate the time it takes for the trains to be kilometers apart using the combined speed.Distance to be apart = kilometersCombined speed = kilometers per hourTime = Distance / SpeedTime = Time hours
- Convert Decimal to Minutes: Convert the decimal part of the hours into minutes.Decimal part of hours Minutes = Decimal part of hours Minutes Minutes Round to the nearest minute: minutes
- Combine Hours and Minutes: Combine the whole number of hours and the rounded minutes to get the final answer.Hours = Minutes = So, it will take approximately hours and minutes for the two trains to be kilometers apart.
