Question

Помогите решить задачу:Со старта велосипедист ехал 3 часа со скоростью 35\ч,и до финиша ему осталось проехать еще 45км.Какой длины была дистанция?.

Answer 1

1) 35*3=105(км)
2) 105+45=150(км)

Answer 2

Х=35*3+45
х=105+45
х=150 км длина всей дистанции

Answer 3

Problem Analysis

To solve this problem, we need to find the total distance traveled by the cyclist. We are given that the cyclist traveled for 3 hours at a speed of 35 km/h and has 45 km remaining to reach the finish line.

Solution

To find the total distance traveled, we can use the formula: distance = speed × time.

Given: - Time = 3 hours - Speed = 35 km/h

We can calculate the distance traveled in the first 3 hours using the formula: distance = speed × time = 35 km/h × 3 hours.

Let's calculate the distance traveled in the first 3 hours: distance = 35 km/h × 3 hours = 105 km.

Now, we need to find the remaining distance to the finish line, which is given as 45 km.

To find the total distance, we add the distance traveled in the first 3 hours to the remaining distance: total distance = distance traveled in the first 3 hours + remaining distance = 105 km + 45 km.

Let's calculate the total distance: total distance = 105 km + 45 km = 150 km.

Therefore, the total distance of the race was 150 km.

Answer

The total distance of the race was 150 km.

Verification

Let's verify the answer using the given information.

We are given that the cyclist traveled for 3 hours at a speed of 35 km/h. Using the formula distance = speed × time, we can calculate the distance traveled in the first 3 hours: distance = 35 km/h × 3 hours = 105 km.

We are also given that the cyclist has 45 km remaining to reach the finish line.

Adding the distance traveled in the first 3 hours to the remaining distance, we get: total distance = 105 km + 45 km = 150 km.

The calculated total distance matches the given information, which verifies that our answer is correct.

Conclusion

The total distance of the race was 150 km.
