Question

Помогите пожалуйста: мотоциклист едет по шоссе со скоростью 45 километров в час.Какое расстояние он проедет за 4 часа. Нужно изменить условие так что бы она стала составной и решить её. Заранее спасибо.

Answer 1

1)45*4=180 (км)-он проедет за 4 часа

Answer 2

Какое расстояние проедет он через 3 часа,если Всё расстояние - 360 км

Answer 3

Calculation of Distance Traveled

To calculate the distance traveled by the motorcyclist, we can use the formula:

Distance = Speed × Time

Given that the motorcyclist is traveling at a speed of 45 kilometers per hour and the time is 4 hours, we can substitute these values into the formula:

Distance = 45 km/h × 4 hours

Calculating this, we find that the motorcyclist will travel a distance of 180 kilometers in 4 hours.

Revised Composite Problem

To create a composite problem, let's modify the original scenario. Suppose the motorcyclist travels at a speed of 45 kilometers per hour for the first 2 hours, and then increases their speed to 60 kilometers per hour for the remaining 2 hours. We need to find the total distance traveled.

To solve this revised problem, we can split it into two parts: the distance traveled at 45 km/h and the distance traveled at 60 km/h. Then, we can add these two distances together to find the total distance.

1. Distance traveled at 45 km/h: - Speed: 45 km/h - Time: 2 hours - Using the formula Distance = Speed × Time, we can calculate the distance traveled at 45 km/h: - Distance = 45 km/h × 2 hours = 90 kilometers

2. Distance traveled at 60 km/h: - Speed: 60 km/h - Time: 2 hours - Using the formula Distance = Speed × Time, we can calculate the distance traveled at 60 km/h: - Distance = 60 km/h × 2 hours = 120 kilometers

3. Total distance traveled: - Adding the distances from step 1 and step 2, we find the total distance traveled: - Total distance = 90 kilometers + 120 kilometers = 210 kilometers

Therefore, in the revised scenario, the motorcyclist will travel a total distance of 210 kilometers.

I hope this helps! Let me know if you have any further questions.
