Question

Старт - одновременно, направление-навстречу. Время движения до встречи 3 часа скорости 45 км/ч и 75 км/ч.Началное расстояние -?????

Answer 1

1)45+75=120(км\ч)
2)120*3=360(км)
Ответ: Начальное расстояние-360 км.

Answer 2

Given Information:

- Two objects start simultaneously from opposite directions. - The time taken for them to meet is 3 hours. - The speeds of the two objects are 45 km/h and 75 km/h.

Calculating the Initial Distance:

To calculate the initial distance between the two objects, we can use the formula:

Initial Distance = (Speed of Object 1 + Speed of Object 2) × Time Taken

Substituting the given values into the formula:

Initial Distance = (45 km/h + 75 km/h) × 3 hours

Calculating the sum of the speeds:

Initial Distance = 120 km/h × 3 hours

Simplifying the calculation:

Initial Distance = 360 km

Therefore, the initial distance between the two objects is 360 km.
