Question

Задача1Метелик і жучок сонечко відпочивали на ромашці .Одночасно вони злетіли з неї і полетіли у протележних напрямках .Через 27с відстань між комахами була 837дм.Швидкість метелика 19дм/с.З якою швидкістю летіло сонечко?Задача2Довжина алеї 540м.Від двох кінців алеї одночасно назустріч один одному побігли Петрик та його песик .Через 2хв Петрик надів на песика новий повідок .З якою швидкістю біг Петрик .якщо швидкість песика була 150м/хв?

Answer 1

1) 19*27=513(м) пролетів метелик

2) 837-513=324(м) пролетіло сонечко

3) 324:2712(дм/с) швидкість сонечка

Відповідь 12дм/с

Answer 2

Problem 1: Метелик і жучок

Given: - Distance between the butterfly and the beetle after 27 seconds: 837 dm - Butterfly's speed: 19 dm/s

To find: - The speed at which the sun was flying

Let's solve this problem step by step:

Step 1: Calculate the distance traveled by the butterfly in 27 seconds. - Distance = Speed × Time - Distance = 19 dm/s × 27 s = 513 dm

Step 2: Calculate the remaining distance between the sun and the beetle after 27 seconds. - Remaining distance = Total distance - Distance traveled by the butterfly - Remaining distance = 837 dm - 513 dm = 324 dm

Step 3: Calculate the time it took for the sun to cover the remaining distance. - Time = Distance / Speed - Time = 324 dm / Speed

Now, we need to find the speed at which the sun was flying. Unfortunately, the problem does not provide any additional information about the sun's speed. Therefore, we cannot determine the exact speed at which the sun was flying.

Problem 2: Петрик та його песик

Given: - Length of the alley: 540 m - Dog's speed: 150 m/min

To find: - Petrik's speed

Let's solve this problem step by step:

Step 1: Calculate the distance traveled by the dog in 2 minutes. - Distance = Speed × Time - Distance = 150 m/min × 2 min = 300 m

Step 2: Calculate the remaining distance between Petrik and the dog after 2 minutes. - Remaining distance = Total distance - Distance traveled by the dog - Remaining distance = 540 m - 300 m = 240 m

Step 3: Calculate the time it took for Petrik to cover the remaining distance. - Time = Distance / Speed - Time = 240 m / Speed

Now, we need to find Petrik's speed. Unfortunately, the problem does not provide any additional information about Petrik's speed. Therefore, we cannot determine the exact speed at which Petrik was running.

In both problems, we are missing crucial information to determine the exact speed of the sun and Petrik.
