Question

90. Петрик вийшов з друзями у двір ліпити снігову бабу об 11 год 10 хв.На велику кулю вони витратять 4 хв,на середню 3 хв, на найменшу 2 хв.Чи встигне Петрик прийти додому о 12 год,якщовони ліпитимуть 5 снігових баб? Скільки сніговихбаб вони встигнуть зліпити?​

Answer 1

Ответ:

Петрик встигне зліпити 5 баб

Пошаговое объяснение:

4хв+3хв+2хв=9хв ліпить одну бабу. 12год-11.10год=55хв у нього є. 9 помножити на 5=45хв. 11.10год+45хв=11.55хв. Тоді зрозуміло, що він зможе зліпити тільки 5 баб. (ця відповідь не точна)

Answer 2

Problem Analysis

The problem involves determining whether Petrik will have enough time to come home by 12:00 if he and his friends make 5 snowmen. Additionally, we need to calculate how many snowmen they will be able to make within the given time frame.

Time Calculation

- Time spent on a large snowball: 4 minutes - Time spent on a medium snowball: 3 minutes - Time spent on a small snowball: 2 minutes

To calculate the total time spent on making 5 snowmen, we can use the following formula: Total time = (Time for large snowball + Time for medium snowball + Time for small snowball) * Number of snowmen

Substituting the given values: Total time = (4 + 3 + 2) * 5 Total time = 9 * 5 Total time = 45 minutes

Conclusion

Petrik and his friends will spend 45 minutes making 5 snowmen. Since they start at 11:10, they will finish at 11:55. Therefore, they will have enough time to come home by 12:00.

Additional Information

If they continue making snowmen, the number of snowmen they can make within the given time frame can be calculated by dividing the total time available by the time taken to make one snowman: Number of snowmen = Total time available / (Time for large snowball + Time for medium snowball + Time for small snowball) Number of snowmen = 50 / (4 + 3 + 2) Number of snowmen = 50 / 9 Number of snowmen ≈ 5.56

Since they cannot make a fraction of a snowman, Petrik and his friends will be able to make 5 snowmen within the given time frame.
