Question

В погоне за брошенным мячом дельфин развил скорость,которая в 5 раз больше скорости морского котика.Кому из них потребуется меньше времени и во сколько раз чтобы проплыть 100м.?Кто из них за одну минуту проплывёт большее расстояние и во сколько раз?

Answer 1

Пусть скорость котика х, тогда скорость дельфина 5х. Тогда время котика t1 = 100\x, время дельфина t2 = 100\5x 
t1\t2 = 5 
Дельфину потребуется меньше времени в 5 раз. 
За 1 минуту большее расстояние проплывёт дельфин. 
S1 = 60·5x = 300x - путь дельфина 
S2 = 60·x - путь котика 
S2\S1 = 1\5 
Расстояние больше в 5 раз 
Удачи!!

Answer 2

Calculating Time and Distance for Dolphin and Seal

To calculate the time and distance for the dolphin and seal, we can use the given information that the dolphin's speed is 5 times greater than the seal's speed.

Speed of the Dolphin (D): 5 times the speed of the Seal (S)

Time to Swim 100m

The time taken by each animal to swim 100m can be calculated using the formula: \[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} \]

Dolphin: \[ \text{Time taken by Dolphin (T\_D)} = \frac{100}{D} \]

Seal: \[ \text{Time taken by Seal (T\_S)} = \frac{100}{S} \]

Distance Covered in One Minute

The distance covered by each animal in one minute can be calculated using the formula: \[ \text{Distance} = \text{Speed} \times \text{Time} \]

Dolphin: \[ \text{Distance covered by Dolphin in 1 minute (D\_D)} = D \times 1 \]

Seal: \[ \text{Distance covered by Seal in 1 minute (D\_S)} = S \times 1 \]

Let's calculate the time and distance for the dolphin and seal using the given information.

Calculation

Given: - Speed of the Dolphin (D): 5 times the speed of the Seal (S)

Using the given information, we can calculate the time and distance for the dolphin and seal.

Time taken by Dolphin (T\_D): \[ T\_D = \frac{100}{D} \]

Time taken by Seal (T\_S): \[ T\_S = \frac{100}{S} \]

Distance covered by Dolphin in 1 minute (D\_D): \[ D\_D = D \times 1 \]

Distance covered by Seal in 1 minute (D\_S): \[ D\_S = S \times 1 \]

Let's calculate the values for \( T\_D \), \( T\_S \), \( D\_D \), and \( D\_S \) using the given information.

Results

Using the given information, we can calculate the values for \( T\_D \), \( T\_S \), \( D\_D \), and \( D\_S \).

Time taken by Dolphin (T\_D): \[ T\_D = \frac{100}{5S} \]

Time taken by Seal (T\_S): \[ T\_S = \frac{100}{S} \]

Distance covered by Dolphin in 1 minute (D\_D): \[ D\_D = 5S \]

Distance covered by Seal in 1 minute (D\_S): \[ D\_S = S \]

Conclusion

- Time taken by Dolphin (T\_D): \( T\_D = \frac{100}{5S} \) - Time taken by Seal (T\_S): \( T\_S = \frac{100}{S} \) - Distance covered by Dolphin in 1 minute (D\_D): \( D\_D = 5S \) - Distance covered by Seal in 1 minute (D\_S): \( D\_S = S \)

Based on the calculations, the time taken by the dolphin and seal to swim 100m and the distance covered by each in one minute can be determined.
