Question

Петя и пять его одноклассников стартовали одновременно в забеге на 100 метров, и Петя пришёл первым. Через 9 секунд после начала забега никто ещё не финишировал, и все его участники в сумме пробежали 290 метров. А когда Петя закончил бег, остальным трём участникам оставалось пробежать до финиша в сумме 100 метров. Сколько метров пробежал Петя за 9 секунд? (Известно, что скорость каждого была постоянной на протяжении всей дистанции)

Answer 1

Може 190 бо я так думаю що це 190 метров 

Answer 2

Calculation of the Distance Run by Petya

To determine the distance run by Petya in 9 seconds, we need to analyze the given information.

According to the problem statement: - Petya and his five classmates started the race simultaneously. - Petya finished first. - After 9 seconds from the start of the race, no one else had finished. - The total distance covered by all participants was 290 meters. - When Petya finished the race, the remaining three participants had a total of 100 meters left to run.

Let's break down the information step by step:

1. Petya finished the race first, and after 9 seconds, no one else had finished. This means that Petya covered the entire distance within the first 9 seconds.

2. The remaining three participants had a total of 100 meters left to run when Petya finished. This implies that the total distance covered by Petya is equal to the total distance minus the 100 meters remaining for the other participants.

3. The total distance covered by all participants is given as 290 meters.

Based on the above information, we can calculate the distance run by Petya in 9 seconds:

Distance run by Petya = Total distance - Distance remaining for other participants

Distance run by Petya = 290 meters - 100 meters

Distance run by Petya = 190 meters

Therefore, Petya ran a distance of 190 meters in 9 seconds.
