Answer 3

Conversion of Hours to Minutes and Seconds

To convert hours to minutes, you multiply the number of hours by 60, since there are 60 minutes in an hour. Similarly, to convert hours to seconds, you multiply the number of hours by 3600, since there are 3600 seconds in an hour.

Let's calculate the conversions:

- 12 hours in minutes: 12 * 60 = 720 minutes. - 150 hours in minutes: 150 * 60 = 9000 minutes. - 400 hours in minutes: 400 * 60 = 24000 minutes.

To convert minutes to seconds, you multiply the number of minutes by 60, since there are 60 seconds in a minute.

- 9 minutes in seconds: 9 * 60 = 540 seconds. - 45 minutes in seconds: 45 * 60 = 2700 seconds. - 128 minutes in seconds: 128 * 60 = 7680 seconds.

Calculation of Grape Harvest

A brigade of 15 people collected 84 boxes of grapes, with each box weighing 14 kg. To calculate the total weight of the grapes, we multiply the number of boxes by the weight of each box.

- Number of boxes: 84 boxes. - Weight of each box: 14 kg.

To calculate the total weight of the grapes, we multiply the number of boxes by the weight of each box:

- Total weight of grapes: 84 boxes * 14 kg = 1176 kg.

To express the result in tons, we divide the total weight of grapes by 1000, since there are 1000 kilograms in a ton:

- Total weight of grapes in tons: 1176 kg / 1000 = 1.176 tons.

Therefore, the brigade collected 1176 kilograms or 1.176 tons of grapes.
