Question

Два велосипедиста выехали навстречу друг другу в 10 ч утра и встретились в 13 ч. Сколько времени был в пути каждый велосипедист?Какое расстояние было между ними первоначально,если один велосепидист ехал со скоростью 16км/ч,а другой - 18км/ч?

Answer 1

13-10=3ч был в пути каждый
16*3=48 проехал один
18*3=54 км проехал другой
48+54=102 км

Answer 2

Calculation of Time and Distance for Each Cyclist

To calculate the time and distance for each cyclist, we can use the formula:

Time = Distance / Speed

Let's calculate the time and distance for each cyclist based on the given information.

Given: - Two cyclists started at 10:00 AM and met at 1:00 PM. - One cyclist was traveling at a speed of 16 km/h, and the other was traveling at a speed of 18 km/h.

To find the time each cyclist spent on the road, we subtract the start time from the meeting time:

- Time spent = Meeting time - Start time - Time spent = 13:00 - 10:00 - Time spent = 3 hours

Now, let's calculate the distance traveled by each cyclist using the formula:

Distance = Speed x Time

For the cyclist traveling at 16 km/h: - Distance = 16 km/h x 3 hours - Distance = 48 km

For the cyclist traveling at 18 km/h: - Distance = 18 km/h x 3 hours - Distance = 54 km

Therefore, each cyclist spent 3 hours on the road, and the distances traveled were 48 km and 54 km, respectively.

Initial Distance Between the Cyclists

To find the initial distance between the cyclists, we need to calculate the distance traveled by each cyclist before they met.

Since we know the time spent by each cyclist and their respective speeds, we can use the formula:

Distance = Speed x Time

For the cyclist traveling at 16 km/h: - Distance = 16 km/h x 3 hours - Distance = 48 km

For the cyclist traveling at 18 km/h: - Distance = 18 km/h x 3 hours - Distance = 54 km

The initial distance between the cyclists can be calculated by subtracting the distance traveled by one cyclist from the distance traveled by the other cyclist:

- Initial distance = Distance of the faster cyclist - Distance of the slower cyclist - Initial distance = 54 km - 48 km - Initial distance = 6 km

Therefore, the initial distance between the two cyclists was 6 km.

Please note that the above calculations are based on the given information and assumptions.
