Question

1 задача два велоиепедиста выехали одновременно из одного посёлка со скоросьтями 16 км/ч и 21 км/ч. На каком расстояние дркг от друга они будут через 4 часа? 2 задач Валера бежит со скоростью 3 м/с. скорость щенка 5 м/с. на каком расстояние друг от друга они будут через 4 часа?

Answer 1

1 задача (21-16)*4=20(км)- друг от друга они будут через 4 часа.
2 задача  (5-3)*60*60*4=28800 метров это 28 км  800 метров.

Answer 2

Task 1:

Two cyclists set out from the same village at speeds of 16 km/h and 21 km/h. The task is to find the distance between them after 4 hours.

To solve this, we can use the formula: Distance = Speed × Time

For the first cyclist: Speed = 16 km/h Time = 4 hours Distance1 = 16 km/h × 4 h = 64 km

For the second cyclist: Speed = 21 km/h Time = 4 hours Distance2 = 21 km/h × 4 h = 84 km

So, the distance between them after 4 hours is the difference between their distances: Distance = Distance2 - Distance1 = 84 km - 64 km = 20 km

Therefore, the two cyclists will be 20 km apart from each other after 4 hours.

Task 2:

Valera runs at a speed of 3 m/s and the puppy runs at a speed of 5 m/s. The task is to find the distance between them after 4 hours.

Using the same formula as before: Distance = Speed × Time

For Valera: Speed = 3 m/s Time = 4 hours Distance_Valera = 3 m/s × 4 h = 12 m

For the puppy: Speed = 5 m/s Time = 4 hours Distance_Puppy = 5 m/s × 4 h = 20 m

So, the distance between them after 4 hours is the difference between their distances: Distance = Distance_Puppy - Distance_Valera = 20 m - 12 m = 8 m

Therefore, Valera and the puppy will be 8 meters apart from each other after 4 hours.
