Question

Погружение на дно озера совершили в 2009г. глубоководные аппараты 《мир -1》 и 《мир-2 》.какой из аппаратов был под водой больше и на сколько ,если 《мир 1》начал погружение в 8 ч. 30 мин.и всплыл в 14ч 30 минут а 《мир-2》 начал погружение в 8 ч 50 мин и всплыл в 16 ч 00 мин.

Answer 1

Мир 1. 14,30-8,30=6час.
Мир 2. 16-8,50=7,10час
7,10-6=1,10час
Ответ: Мир 2 больше, на 1час10мин.

Answer 2

Deep Dive to the Bottom of the Lake in 2009

In 2009, two deep-sea submersibles, "Mir-1" and "Mir-2," conducted a dive to the bottom of the lake. The question asks which of the submersibles spent more time underwater and by how much, given that "Mir-1" began its descent at 8:30 AM and resurfaced at 2:30 PM, while "Mir-2" started its descent at 8:50 AM and resurfaced at 4:00 PM.

To determine which submersible spent more time underwater, we can calculate the duration of each submersible's dive.

Duration of "Mir-1" Dive

- Start time: 8:30 AM - End time: 2:30 PM

To calculate the duration, we subtract the start time from the end time:

2:30 PM - 8:30 AM = 6 hours

Therefore, "Mir-1" spent 6 hours underwater.

Duration of "Mir-2" Dive

- Start time: 8:50 AM - End time: 4:00 PM

To calculate the duration, we subtract the start time from the end time:

4:00 PM - 8:50 AM = 7 hours and 10 minutes

Therefore, "Mir-2" spent 7 hours and 10 minutes underwater.

Comparison of Dive Durations

- "Mir-1" spent 6 hours underwater. - "Mir-2" spent 7 hours and 10 minutes underwater.

Therefore, "Mir-2" spent more time underwater than "Mir-1" by 1 hour and 10 minutes.

Please note that the information provided is based on the given start and end times for the dives of "Mir-1" and "Mir-2."
