Question

Пеппи отправила свой катер в путешествие по канаве длиной 800 метров. Первые 5 мин он плыл со скоростью 100м/мин, а затем со скоростью 50м/мин.за сколько времени катер преодолел канаву с водой

Answer 1

100*5=500(км)- проплыл со скор. 100м/мин
800-500=300(км)-проплыл со скор. 50м/мин
300:50=6(мин)-проплыл со скор. 50м/мин
5+6=11(мин)
ОТВЕТ:за 11 минут

Answer 2

1) 100 х 5 = 500 метров проплыл катер со скоростью 100 м/мин
2) 800-500= 300 метров проплыл катер со скоростью 50 м/мин
3) 300 : 50 =6 минут катер плыл со скоростью 50 м/мин
4) 5 + 6 = за 11 минут катер проплыл канаву с водой.

Answer 3

Calculation of Time Taken to Travel the Canal

To calculate the time taken for the boat to travel the canal, we need to consider the distances covered at different speeds.

The boat first travels at a speed of 100 meters per minute for the first 5 minutes. This means it covers a distance of 100 meters per minute for 5 minutes, which is a total distance of 100 meters/minute * 5 minutes = 500 meters.

After the first 5 minutes, the boat travels at a speed of 50 meters per minute. Since the total length of the canal is 800 meters and the boat has already covered 500 meters, it needs to cover an additional distance of 800 meters - 500 meters = 300 meters.

To calculate the time taken to cover this additional distance, we can use the formula:

Time = Distance / Speed

Plugging in the values, we have:

Time = 300 meters / 50 meters per minute = 6 minutes

Therefore, the total time taken for the boat to travel the canal is 5 minutes + 6 minutes = 11 minutes.
