Question

Помогите с задачей! Две верёвки связали вместе. Длина каждой-17м.40см. Затем привязали ещё одну верёвку так, что общая длина стала 67м.85см. На сколько увеличилось при этом общая длина верёвки?

Answer 1

17м40см+17м40см=34м80см
67м85см-34м80см=33м05см
Общая длина веревки увеличилась на 33м05см

Answer 2

Problem Analysis

To solve this problem, we need to find the increase in the total length of the rope after adding another rope to two ropes with a combined length of 17m 40cm each.

Solution

Let's break down the problem step by step:

1. The length of each of the two ropes is 17m 40cm. 2. The total length of the two ropes is 2 * 17m 40cm = 34m 80cm. 3. Another rope is added to the two ropes, making the total length 67m 85cm.

To find the increase in the total length, we subtract the initial total length from the final total length:

67m 85cm - 34m 80cm = 33m 5cm.

Therefore, the total length of the rope increased by 33m 5cm.

Conclusion

The total length of the rope increased by 33 meters and 5 centimeters after adding another rope to two ropes with a combined length of 17 meters and 40 centimeters each.
