Question

1) 5м52 см + 2 м 64 см = 2) 12 мин 15 сек - 5 мин 39 с =

Answer 1

Ответ: 8 м 16 см

6 мин 36 сек

Пошаговое объяснение:

1 м = 100 см

5 м 52 см = 552 см

2 м 64 см = 264 см

552 + 264 = 816 см = 8 м 16 см

12 мин 15 сек - 5 мин 39 сёк

1 мин = 60 сек

12 мин 15 сёк = (12 × 60) + 15 = 720 +15 = 735 сек

5 мин 39 сек = (5 ×60) +39 = 300 + 39 = 339

735 - 339 = 396 сек = (60 ×6 = 360) (396 - 360 = 36 сёк) 6 мин 36 сек

Answer 2

1. To add these measurements, we need to ensure that the units are consistent. Let's convert everything to centimeters:

5m 52cm = (5 * 100) cm + 52 cm = 500 cm + 52 cm = 552 cm

2m 64cm = (2 * 100) cm + 64 cm = 200 cm + 64 cm = 264 cm

Now we can add them together:

552 cm + 264 cm = 816 cm

Therefore, 5m 52cm + 2m 64cm = 816 cm.

2. To subtract these measurements, we also need consistent units. Let's convert everything to seconds:

12 min 15 sec = (12 * 60) sec + 15 sec = 720 sec + 15 sec = 735 sec

5 min 39 sec = (5 * 60) sec + 39 sec = 300 sec + 39 sec = 339 sec

Now we can subtract them:

735 sec - 339 sec = 396 sec

Therefore, 12 min 15 sec - 5 min 39 sec = 396 sec.
