Question

жираф пробежал 100м за 7с.сможет ли он пробежать 1км за 1мин если будет двигаться с той же скоростью

Answer 1

1км он пробежит за 70сек=1мин 10 сек   значит не сможет

Answer 2

Calculation of Giraffe's Speed

To determine if the giraffe can run 1 km in 1 minute at the same speed it ran 100 m in 7 seconds, we need to calculate its speed in meters per second.

Given: - Distance covered: 100 m - Time taken: 7 seconds

To calculate the speed, we use the formula:

Speed = Distance / Time

Substituting the given values:

Speed = 100 m / 7 s

Calculating the speed:

Speed = 14.29 m/s (rounded to two decimal places)

Can the Giraffe Run 1 km in 1 Minute?

Now, let's determine if the giraffe can run 1 km in 1 minute at the same speed.

Given: - Distance to cover: 1 km - Time available: 1 minute

To calculate the speed required to cover 1 km in 1 minute, we use the formula:

Speed = Distance / Time

Substituting the given values:

Speed = 1 km / 1 min

Converting 1 km to meters:

Speed = 1000 m / 1 min

Calculating the speed:

Speed = 1000 m/min

To compare this speed with the giraffe's speed, we need to convert it to meters per second. Since there are 60 seconds in a minute, we divide the speed by 60:

Speed = 1000 m / 60 s

Calculating the speed:

Speed = 16.67 m/s (rounded to two decimal places)

Conclusion

The giraffe's speed is 14.29 m/s, while the speed required to cover 1 km in 1 minute is 16.67 m/s. Therefore, the giraffe cannot run 1 km in 1 minute at the same speed it ran 100 m in 7 seconds
