Question

Из 2 городов выехали одновременно навстречу друг другу 2 мотоциклиста.Один из них двигался со скоростью 80/ч и проехал 160 км, а другой двигался со средней скоростью 75/ч найти расстояние между городами

Answer 1

1)160\80=2(ч)был в пути 1 мотоциклист
2)2*75=150(км)расстояние между ними
3)160+150=310(км)расстояние

Answer 2

1)160/80=2(ч) 2)75*2=150 3)150+160=310.

Answer 3

Problem Analysis

Two motorcyclists start from two different cities and travel towards each other. We are given the speed of each motorcyclist and the distance traveled by one of them. We need to find the distance between the two cities.

Given Information

- Motorcyclist 1: Speed = 80 km/h, Distance traveled = 160 km - Motorcyclist 2: Speed = 75 km/h

Calculation

To find the distance between the two cities, we can use the formula:

Distance = Speed × Time

Let's calculate the time taken by each motorcyclist to travel the given distance.

For Motorcyclist 1: Time = Distance / Speed = 160 km / 80 km/h = 2 hours

For Motorcyclist 2: Time = Distance / Speed = ? / 75 km/h

Since both motorcyclists started at the same time and met each other, the total time taken by both motorcyclists is the same. Therefore, the time taken by Motorcyclist 2 is also 2 hours.

Now, we can find the distance between the two cities using the time taken by Motorcyclist 2 and their speed.

Distance = Speed × Time = 75 km/h × 2 hours = 150 km

Answer

The distance between the two cities is 150 km.
