Question

Дети проводили испытание воздушного змея. В первый раз он продержался в воздухе 5 мин. 23 сек., во второй- 5 мин. 27 сек., а в третий-7 мин. 10 сек. Сколько времени в среднем воздушный змей находился в воздухе?

Answer 1

(5 мин.23 сек+5мин. 27сек+7 мин..10сек)÷3=18 мин.÷3=6 мин.

Answer 2

Calculating Average Time in the Air for the Kite

To calculate the average time the kite spent in the air, we can add up the total time the kite was in the air and then divide by the number of trials.

- First attempt: 5 minutes 23 seconds - Second attempt: 5 minutes 27 seconds - Third attempt: 7 minutes 10 seconds

Calculation

To find the average time, we add up the total time and divide by 3 (the number of trials):

5 minutes 23 seconds + 5 minutes 27 seconds + 7 minutes 10 seconds = 17 minutes 60 seconds + 60 seconds = 18 minutes 60 seconds = 19 minutes 0 seconds

Dividing by 3:

19 minutes 0 seconds / 3 = 6 minutes 20 seconds

The average time the kite spent in the air was 6 minutes and 20 seconds.
