Question

Егіс даласынаң картоп тиеген екі машина шықты.Олар таңғы сағат 8.00-де шығып,бір бағытта жүреді.Сағат 10.00-де олардың ара қашықтығы 4 км болды.Егер екіншісінде жылдамдығы 50км/сағ болса,онда бірінші жүк машинасы кандай жылдамдықпен жүрлі?

Answer 1

Calculation of Speed:

To determine the speed of the first truck, we can use the formula:

Speed = Distance / Time

Given that the distance between the two trucks is 4 km and the time taken is 2 hours (from 8:00 to 10:00), we can calculate the speed of the second truck:

Speed = 4 km / 2 hours = 2 km/h

Therefore, the speed of the second truck is 2 km/h.

Relationship between the Speeds of the Two Trucks:

To find the speed of the first truck, we need to determine the relationship between the speeds of the two trucks. We are given that the speed of the second truck is 50 km/h.

Let's assume that the speed of the first truck is x km/h. Since the two trucks are traveling in the same direction, the relative speed between them is the difference between their speeds:

Relative Speed = Speed of Second Truck - Speed of First Truck

In this case, the relative speed is 50 km/h - x km/h.

We know that the relative speed is equal to the distance between the two trucks divided by the time taken:

Relative Speed = 4 km / 2 hours = 2 km/h

Setting these two expressions for the relative speed equal to each other, we can solve for x:

50 km/h - x km/h = 2 km/h

Simplifying the equation, we get:

48 km/h = x km/h

Therefore, the speed of the first truck is 48 km/h.

Conclusion:

The first truck is traveling at a speed of 48 km/h.
