Question

От одной пристани одновременно в противоположный направлениях отошли 2 теплохода со скоростью 40км/ч и 60км/ч соответственно .Какое расстояние ьыло между ними когда первый теплоход прошёл 120км?

Answer 1

120:40=3 часа ушёл первый пароход
60*3=180 км прошёл второй
120+180=300км
Расстояние между ними будет 300 км

Answer 2

Calculation of the Distance between the Two Ships

To calculate the distance between the two ships when the first ship has traveled 120 km, we can use the formula:

Distance = Speed × Time

Let's calculate the time it takes for the first ship to travel 120 km:

Time = Distance / Speed

For the first ship with a speed of 40 km/h:

Time1 = 120 km / 40 km/h = 3 hours

Now, let's calculate the distance traveled by the second ship in 3 hours:

Distance2 = Speed2 × Time1 = 60 km/h × 3 hours = 180 km

Therefore, when the first ship has traveled 120 km, the distance between the two ships is 180 km.

Please note that the above calculations are based on the assumption that the two ships maintain a constant speed and travel in opposite directions from the same starting point.
