Tag, guys, is this correct?. Vielen Dank. A freight train and an express train leave towns 390km apart, traveling toward one another. The freight train travels 30km per hour slower than the express train. They pass each other 3 hours later. What are the speeds of the freight and express train respectively?. Freight data distance kms apart from the other train time hrs Speed kmph Express data distance kms apart from the other train time hrs (the time it takes for them to pass each other) Speed= then, Speed of express - Speed of freight kmph mph km this is the distance that the freight train has traveled kmph (rate of speed of the freight train) then to find distance for the express, this is the distance that the express train has traveled now to find the rate of the speed for the express kmph so the freight train was going at a rate of kmph the express train was going at kmph.

Zum Vergleich meine Rechnung mit Einsetzen: Gschwindigkeit expresstrain, Geschwindigkeit freight train jeweils in Ich denke, das ist leicht nachvollziehbar und vlt. etwas einfacher. |
