Question

За 12 с участник школьных соревнований пробежал 60м если он будет бежать с той же скоростью то за сколько секунд он пробежит 40 м 100 м за какое время пробежит 200м спортсмен скорость которого в 2 раза больше

Answer 1

=60:12=5( метров в секунду)
40:5=8 (секунд)
100:5=20 (секунд)
200:5=40 
40:2=20 (секунд)
Ответ: 8,20,20

Answer 2

Calculation of Time to Run Different Distances

To calculate the time it takes for the participant to run different distances, we need to know the speed at which they are running. The question states that the participant ran 60 meters in 12 seconds. We can use this information to calculate their speed.

The formula to calculate speed is:

Speed = Distance / Time

Using the given values, we can calculate the speed:

Speed = 60 meters / 12 seconds = 5 meters per second.

Now, let's calculate the time it takes for the participant to run different distances:

1. Time to run 40 meters:

Using the speed calculated above, we can calculate the time it takes to run 40 meters:

Time = Distance / Speed = 40 meters / 5 meters per second = 8 seconds.

Therefore, it will take the participant 8 seconds to run 40 meters.

2. Time to run 100 meters:

Using the same speed, we can calculate the time it takes to run 100 meters:

Time = Distance / Speed = 100 meters / 5 meters per second = 20 seconds.

Therefore, it will take the participant 20 seconds to run 100 meters.

3. Time to run 200 meters:

The question introduces another participant whose speed is twice that of the first participant. Therefore, their speed would be:

Speed = 2 * 5 meters per second = 10 meters per second.

Using this speed, we can calculate the time it takes to run 200 meters:

Time = Distance / Speed = 200 meters / 10 meters per second = 20 seconds.

Therefore, it will take the second participant 20 seconds to run 200 meters.

To summarize: - The first participant will take 8 seconds to run 40 meters, 20 seconds to run 100 meters, and 20 seconds to run 200 meters. - The second participant will take 20 seconds to run 200 meters.

Please note that these calculations assume a constant speed throughout the entire distance and do not take into account factors such as acceleration or deceleration.
