From two shelters, the distance between them is 142 km, two bumblebees flew towards each other at the same time.

From two shelters, the distance between them is 142 km, two bumblebees flew towards each other at the same time. The speed of one bumblebee is 25 km / h. At what speed the bumblebee flew if they met after 2 hours.

Let’s denote the speed of the second bumblebee by the letter X. When moving towards the opposite, the speeds add up. In our case, the total speed will be equal to X + 25. Since the distance between them was initially equal to 142 km and they flew for 2 hours, we can write the equation:
(25 + X) x 2 = 142.
Let’s solve it:
25 + X = 71;
X = 46 (km / h).
Answer: the second bumblebee flew at a speed of 46 km / h.
