Question

Турист На автобусе а км/ч, 3 ч со скоростью ,b км/ч и 2 ч шел пешком со скоростью. Турист какая средная скорость. Где а=50;b=5 Турист автобуспен а км/сағ жылдамдықпен 3 сағ жүрген соң, b км/сағ жылдамдықпен 2 сағ жаяу жүрді. Турист қандай орташа жылдамдықпен жүрді. Мұндағы а=50;b=5

Answer 1

А×3ч=50км/час×3час=150км
b×2час=5км/час×2час=10км
3час+2час=5часа
150км+10км=160км
160км÷5час=32км/час
ответ: средная скорость 32км/час

Answer 2

Calculation of Average Speed

To calculate the average speed of the tourist, we need to find the total distance traveled and the total time taken.

The tourist traveled a kilometers per hour on the bus for 3 hours and b kilometers per hour on foot for 2 hours.

The total distance traveled on the bus is a * 3 kilometers, and the total distance traveled on foot is b * 2 kilometers.

The total time taken is 3 hours on the bus and 2 hours on foot, which is a total of 5 hours.

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

Average Speed = (Total Distance) / (Total Time)

Substituting the values, we get:

Average Speed = ((a * 3) + (b * 2)) / 5

Given that a = 50 and b = 5, we can calculate the average speed.

Let's calculate it:

Average Speed = ((50 * 3) + (5 * 2)) / 5

Average Speed = (150 + 10) / 5

Average Speed = 160 / 5

Average Speed = 32 kilometers per hour

Therefore, the average speed of the tourist is 32 kilometers per hour.
