Question

принтер печатает 80 снимков за час. Оператор включил печать в 11.45 и выключил принтер в четверь третьего. Сколько снимков он смог сделать за это время??

Answer 1

С 11:45 до 14:15 (четверть третьего) = 2,5 часа

За 1 час - 80 снимков
2,5*80=200 (снимков) - за 2,5 часа.

Ответ: 200 снимков.

Answer 2

Calculation of the Number of Photos Printed

To calculate the number of photos printed, we need to determine the duration of time the printer was active. The operator turned on the printer at 11:45 and turned it off at a quarter to three.

To find the duration, we subtract the start time from the end time:

End time: a quarter to three = 2:45 PM Start time: 11:45 AM

To calculate the duration, we subtract the start time from the end time:

2:45 PM - 11:45 AM = 3 hours

Therefore, the printer was active for 3 hours.

Now, we need to calculate the number of photos printed in this time frame. We are given that the printer can print 80 photos per hour.

To find the total number of photos printed, we multiply the number of photos printed per hour (80) by the number of hours the printer was active (3):

80 photos/hour * 3 hours = 240 photos

Therefore, the operator was able to print 240 photos during the time the printer was active.
