Question

Пухнастики вместе разлетелись в разные разные стораны .Скорость первого 45км/ч , а второго на 7 км/ч больше .Какое расстояние будет между ними ,если первый пролетел 120 мин, а второй 2 часа?

Answer 1

1. Находим скорость второго пухнастика: 45+7=52 км/ч 2. Так как пухнастики разлетаются в разные стороны, то каждый час расстояние между ними увеличивается на: 45+52=97 км 3. 120 минут полета и 2 часа полета - одинаковые величины 4. За 2 часа разлета расстояние между пухнастиками будет: 2*97=194 км

Answer 2

Problem Analysis

We are given the speeds of two objects, the time each object traveled, and the fact that the second object's speed is 7 km/h greater than the first object's speed. We need to find the distance between the two objects.

Solution

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

Distance = Speed × Time

Let's calculate the distance traveled by each object and then find the difference between their distances.

1. Calculate the distance traveled by the first object: - Speed of the first object = 45 km/h - Time traveled by the first object = 120 minutes = 2 hours - Distance traveled by the first object = Speed × Time = 45 km/h × 2 hours

2. Calculate the distance traveled by the second object: - Speed of the second object = Speed of the first object + 7 km/h - Time traveled by the second object = 2 hours - Distance traveled by the second object = Speed × Time = (45 km/h + 7 km/h) × 2 hours

3. Find the difference between the distances traveled by the two objects: - Difference in distance = Distance traveled by the second object - Distance traveled by the first object

Let's calculate the values step by step.

Calculation

1. Calculate the distance traveled by the first object: - Speed of the first object = 45 km/h - Time traveled by the first object = 2 hours - Distance traveled by the first object = 45 km/h × 2 hours = 90 km

2. Calculate the distance traveled by the second object: - Speed of the second object = 45 km/h + 7 km/h = 52 km/h - Time traveled by the second object = 2 hours - Distance traveled by the second object = 52 km/h × 2 hours = 104 km

3. Find the difference between the distances traveled by the two objects: - Difference in distance = 104 km - 90 km = 14 km

Answer

The distance between the two objects is 14 km.
