Question

Во время соревновании два спортсмена стартовали в 11часов 6 минут.один из них пробежал дистанцию за 1 минуту 57 секунд ,а другой пришел к финишу на 5 секунд позже.какое показывало время секундомера когда прибежал второй спортсмен?сколько времени показывали часы,когда прибежал каждый из них?

Answer 1

1 мин 57 сек + 5 сек=2 мин 2 сек
11 часов 6 минут + 2 мин 2 сек =11 часов 8 мин 2 сек
ответ:11часов 8 минут 2 секунды

Answer 2

Calculation of the Stopwatch Time

To determine the time shown on the stopwatch when the second athlete crossed the finish line, we need to calculate the time difference between the two athletes.

The first athlete completed the race in 1 minute and 57 seconds, while the second athlete finished 5 seconds later. Therefore, the time difference between the two athletes is 5 seconds.

To find the time shown on the stopwatch when the second athlete finished, we need to subtract the time difference from the total time of the first athlete.

The total time of the first athlete is 1 minute and 57 seconds, which is equivalent to 117 seconds (1 minute * 60 seconds + 57 seconds).

Subtracting the time difference of 5 seconds from the total time of the first athlete, we get:

117 seconds - 5 seconds = 112 seconds.

Therefore, the stopwatch time when the second athlete crossed the finish line was 112 seconds.

Calculation of the Clock Time

To determine the time shown on the clock when each athlete finished the race, we need to add the race time to the starting time.

The athletes started the race at 11:06 AM.

The first athlete completed the race in 1 minute and 57 seconds. Adding this time to the starting time:

11:06 AM + 1 minute and 57 seconds = 11:08 AM and 57 seconds.

Therefore, the clock time when the first athlete finished the race was 11:08 AM and 57 seconds.

The second athlete finished the race 5 seconds after the first athlete. Adding this time to the starting time:

11:06 AM + 5 seconds = 11:06 AM and 5 seconds.

Therefore, the clock time when the second athlete finished the race was 11:06 AM and 5 seconds.

Please note that the clock time is based on the given starting time and the race times provided.
