Question

Петя пробегает 300м за 6 секунд, а Коля тоже расстояние пробегает за 5 секунд. На сколько м/с скорость Коли быстрее скорости Пети?

Answer 1

1) 300:6=50м/сек- скорость Пети
2)300:5=60м/сек- скорость Коли
3) 60-50=10м/сек- разница

Answer 2

Calculation of Speed

To calculate the speed of Petya and Kolya, we need to divide the distance they run by the time it takes for them to run that distance.

Petya runs 300 meters in 6 seconds, so his speed can be calculated as:

Petya's speed = Distance / Time = 300 meters / 6 seconds = 50 meters per second.

Kolya runs the same distance of 300 meters, but he does it in 5 seconds. Therefore, his speed can be calculated as:

Kolya's speed = Distance / Time = 300 meters / 5 seconds = 60 meters per second.

Comparison of Speeds

To determine how much faster Kolya is compared to Petya, we can subtract Petya's speed from Kolya's speed:

Difference in speed = Kolya's speed - Petya's speed = 60 meters per second - 50 meters per second = 10 meters per second.

Therefore, Kolya is 10 meters per second faster than Petya.
