Question

Фотопринтер печатает 80 снимков в час. Оператор включил печать в 11.45 и включил фотопринтер в четверть третьего. Сколько снимков напечатал фотопринтер за это время?

Answer 1

14.15-11.45=2.30 минут был включен принтер

80:2=40 cнимков в 30 минут

80+80+40=200 снимков

Answer 2

Время - 11:45-14:15 -> 2,5 часа
80*2,5 = 200

Answer 3

Calculation of the Number of Photos Printed

To calculate the number of photos printed by the photo printer, we need to determine the duration of time between 11:45 and a quarter past three (15:15).

The time between 11:45 and 15:15 is approximately 3 hours and 30 minutes.

Since the photo printer can print 80 photos per hour, we can calculate the total number of photos printed by multiplying the number of hours by the printing speed:

3.5 hours * 80 photos/hour = 280 photos.

Therefore, the photo printer would have printed approximately 280 photos during this time period.

Please note that the exact number of photos printed may vary depending on the specific performance and efficiency of the photo printer.
