Two boats left in opposite directions when the first one drove 840m at a speed of 120km / h, the distance between them became 1km890m Was the second boat moving at a speed?
1. Let’s find how much time the first boat spent on its way, dividing the distance by the speed.
120 km / h = 2000 m / min
840/2000 = 0.42 minutes spent on the first boat.
2. Find the path of the second boat by subtracting the path of the first boat from the distance between the boats.
1 km 890 m = 1890 m.
1890 – 840 = 1050 meters covered by the second boat.
3. Let’s find the speed with which the second boat was traveling, dividing the distance traveled by it by time.
1050 / 0.42 = 2500 m / min speed of the second boat.
We translate 2500 m / min = 150 km / h
Answer: 150 km / h.
