Question

Из одной норки одновременно в противоположных направлениях побежали две ящерицы . На каком расстоянии друг от друга будут ящерицы через 4 мин 12сек, если первая бежала со скоростью 7м/с а вторая на 1м/с медленнее?

Answer 1

252 секунды общее время

7 умножить на 252 = 1764 метров

6 умножить на 252 = 1512 метров

1764+1512=3276

Answer 2

Calculation of the Distance Between Lizards

To calculate the distance between the two lizards after 4 minutes and 12 seconds, we need to determine the distance each lizard has traveled during that time.

The first lizard runs at a speed of 7 m/s, while the second lizard runs 1 m/s slower, at a speed of 6 m/s.

To find the distance traveled by each lizard, we can use the formula:

Distance = Speed × Time

For the first lizard: Distance1 = 7 m/s × (4 minutes + 12 seconds)

For the second lizard: Distance2 = 6 m/s × (4 minutes + 12 seconds)

Now, let's convert the time into seconds for easier calculation:

4 minutes = 4 × 60 seconds = 240 seconds 12 seconds = 12 seconds

Substituting the values into the formulas:

Distance1 = 7 m/s × (240 seconds + 12 seconds) Distance2 = 6 m/s × (240 seconds + 12 seconds)

Calculating the distances:

Distance1 = 7 m/s × 252 seconds = 1764 meters Distance2 = 6 m/s × 252 seconds = 1512 meters

Therefore, after 4 minutes and 12 seconds, the two lizards will be 1512 meters apart from each other
