Question

Арман вышел из дома в 8 часов и пришел в школу в 8.30. Расстояние от школы до дома 1 км 500 м. Какова скорость движения Армана?

Answer 1

1) 8ч 30 мин - 8ч = 30 мин= 0,5 ч
2) 1 км 500 м = 1,5 км
3) 1,5:0,5= 3 км/ч
Ответ: скорость движения Армана 3 км/ч

Answer 2

8-8.30=30 (мин.) от школы до дома t.
1,5 км/30мин, то 3 км/ч
Ответ средняя скорость движения 3 км/ч

Answer 3

Calculation of Arman's Speed

To calculate Arman's speed, we need to determine the time it took for him to travel from home to school and the distance between the two locations.

Given information: - Arman left home at 8:00 AM. - Arman arrived at school at 8:30 AM. - The distance from school to home is 1 kilometer and 500 meters.

To calculate the time it took for Arman to travel, we subtract the departure time from the arrival time:

Time taken = Arrival time - Departure time Time taken = 8:30 AM - 8:00 AM Time taken = 30 minutes

Now that we know the time taken, we can calculate Arman's speed using the formula:

Speed = Distance / Time

Substituting the values we have: Speed = 1.5 kilometers / 30 minutes

To convert the time from minutes to hours, we divide by 60: Speed = 1.5 kilometers / (30 minutes / 60 minutes per hour) Speed = 1.5 kilometers / 0.5 hours Speed = 3 kilometers per hour

Therefore, Arman's speed of movement is 3 kilometers per hour.
