Question

Велосепедист ехал со скоростью 11 км ч а автомобиль в 7 раз больше найдите расстояние между городами если они выехали друг на друга а встретелись через 4 часа

Answer 1

Скорость велосипедиста 11 км/ч

11*7=77- скорость автомобиля

11*4=44-км проехал велосипедист

77*4=308 км проехал автомобиль

308+44=352 км расстояние между городами

Answer 2

352 км между городами

Answer 3

Problem Analysis

We are given that a cyclist is traveling at a speed of 11 km/h, while a car is traveling at a speed 7 times greater. We need to find the distance between the two cities if they started from each other and met after 4 hours.

Solution

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

Distance = Speed × Time

Let's calculate the distance traveled by the cyclist and the car separately.

The cyclist's speed is given as 11 km/h, and the time traveled is 4 hours. Therefore, the distance traveled by the cyclist is:

Distance_cyclist = Speed_cyclist × Time = 11 km/h × 4 h = 44 km The car's speed is 7 times greater than the cyclist's speed, so the car's speed is:

Speed_car = 7 × Speed_cyclist = 7 × 11 km/h = 77 km/h

Now, we can calculate the distance traveled by the car:

Distance_car = Speed_car × Time = 77 km/h × 4 h = 308 km Since the cyclist and the car started from each other, the total distance between the two cities is the sum of the distances traveled by the cyclist and the car:

Total_distance = Distance_cyclist + Distance_car = 44 km + 308 km = 352 km

Therefore, the distance between the two cities is 352 kilometers.

Answer

The distance between the two cities is 352 kilometers.
