Question

Из двух укрытий расстояние между которыми 142км, одновременно навстречу друг другу вылетели два шмеля Скорость одного шмеля 25км/ч., С какой скоростью летел шмель если они встретились через 2часа

Answer 1

25*2=50 км  за 2 часа пролетел первый шмель                                                  142-50=92 км расстояния между 2 шмелями                                                      92:2=46 км/час скорость второго шмеля

Answer 2

Problem Analysis

We have two bees flying towards each other from two different locations, with a distance of 142 km between them. One bee is flying at a speed of 25 km/h. We need to find the speed at which the other bee is flying if they meet after 2 hours.

Solution

To solve this problem, we can use the formula: distance = speed × time.

Let's assume the speed of the second bee is x km/h.

The first bee travels for 2 hours at a speed of 25 km/h, so the distance it covers is 25 km/h × 2 h = 50 km.

The second bee also travels for 2 hours at a speed of x km/h, so the distance it covers is x km/h × 2 h = 2x km.

Since the total distance between the bees is 142 km, we can set up the equation:

50 km + 2x km = 142 km

Simplifying the equation:

2x km = 142 km - 50 km

2x km = 92 km

Dividing both sides of the equation by 2:

x km = 92 km / 2

x km = 46 km/h

Therefore, the second bee is flying at a speed of 46 km/h.

Answer

The second bee is flying at a speed of 46 km/h.

Verification

Let's verify the answer using the given information:

- The first bee flies at a speed of 25 km/h for 2 hours, covering a distance of 50 km. - The second bee flies at a speed of 46 km/h for 2 hours, covering a distance of 92 km. - The total distance covered by both bees is 50 km + 92 km = 142 km, which matches the given distance between the two locations.

Therefore, the answer is verified.
