Question

Перші 3 км велосипедист проїхав за чат 12 хв, а наступні 4 км- за 0,5 год. Якою була середня швидкість на всьому шляху? Відповідь записати у км/год

Answer 1

Ответ:

L1 - 3км | 12 хв - 0,2 год

T1 - 12хв| L= l1+l2

T1 - 4км | t=3км+ 4км= 7 км

T2 - 0,5 |t=0,2+0,5=0,7год

U -? |UC= 2

| 7

| Uc= 7км =10 км/год

| 0,7год

| Uc=10кл/ год

Объяснение:

Відповідь 10км/ год

Answer 2

Calculation of Average Speed

To calculate the average speed, we need to find the total distance traveled and the total time taken. In this case, the cyclist traveled 3 km in 12 minutes and 4 km in 0.5 hours.

Let's convert the time taken for the first part of the journey from minutes to hours. We know that 1 hour is equal to 60 minutes, so 12 minutes is equal to 12/60 = 0.2 hours.

Now, we can calculate the total distance traveled and the total time taken:

- Distance: 3 km + 4 km = 7 km - Time: 0.2 hours + 0.5 hours = 0.7 hours

To find the average speed, we divide the total distance by the total time:

Average Speed = Total Distance / Total Time

Average Speed = 7 km / 0.7 hours

Calculation

Let's calculate the average speed:

Average Speed = 7 km / 0.7 hours = 10 km/h

Therefore, the average speed for the entire journey was 10 km/h.
