Question

За 95 минут человек пробежал 30 км.. За какое время он пробежит 100 метров?

Answer 1

Составим пропорцию по условию задачи:

95 мин - 30000

x мин - 100 м

x = 100 * 95/30000 = 19/60(мин) = 19 сек.

Ответ: 19 сек.

Answer 2

Дано:                                                            Решение:

t = 95 мин = 5700 с

S = 30 км = 30 000 м               Так как скорость бега постоянная, то:

S₁ = 100 м                                           S/t = S₁/t₁ =>

------------------------------                    => t₁ = S₁t/S = 100*5700:30000 = 57 : 3 = 19 (с)

Найти: t₁ - ?

Ответ: 19 с.

Answer 3

To find out how long it would take the person to run 100 meters, we can use the given information about their running speed.

Let's first find the person's running speed in kilometers per minute:

Speed = Distance / Time

Speed = 30 km / 95 min ≈ 0.3158 km/min

Now, we need to convert this speed to meters per minute, as the distance given (100 meters) is in meters:

1 kilometer = 1000 meters

Speed = 0.3158 km/min * 1000 m/km ≈ 315.8 m/min

Now, we can calculate the time it would take to run 100 meters at this speed:

Time = Distance / Speed

Time = 100 m / 315.8 m/min ≈ 0.3166 min

Finally, let's convert the time back to seconds for a more convenient representation:

0.3166 minutes * 60 seconds/minute ≈ 19.0 seconds

So, the person would take approximately 19.0 seconds to run 100 meters at this speed.
