Question

Мотоциклист проехал 180 километров какое расстояние может проехать за то же время велосипедист если выходит составляет 1 4 скорости мотоциклиста Какова скорость мотоциклиста если скорость велосипедиста 15 километров в час

Answer 1

1) 15*4=60 км/ч скорость мотоциклиста
2) 180:60=за 3 часа мотоциклист проезжает 180 км
3) 15*3=45 км может проехать велосипедист за то же время
Ответ: 60 км/ч и 45 км

Answer 2

Calculating the Bicyclist's Speed

To calculate the distance the bicyclist can travel in the same time the motorcyclist traveled 180 kilometers, we can use the formula:

distance = speed × time

Given that the motorcyclist traveled 180 kilometers, we need to find the distance the bicyclist can travel in the same time. We are also given the ratio of the speeds of the motorcyclist and the bicyclist, which is 4:1.

Using the ratio of speeds, we can calculate the distance the bicyclist can travel in the same time as the motorcyclist using the following steps:

1. Calculate the time taken by the motorcyclist to travel 180 kilometers: - We need to know the time taken by the motorcyclist to cover the given distance.

2. Use the ratio of speeds to find the distance the bicyclist can travel in the same time: - Once we have the time taken by the motorcyclist, we can use the ratio of speeds to find the distance the bicyclist can travel in the same time.

Calculating the Motorcyclist's Speed

Given that the speed of the bicyclist is 15 kilometers per hour, we can use the ratio of speeds to find the speed of the motorcyclist.

Let's calculate the time taken by the motorcyclist to travel 180 kilometers and then find the distance the bicyclist can travel in the same time. After that, we can use the ratio of speeds to calculate the speed of the motorcyclist.

Solution

1. Calculate the time taken by the motorcyclist to travel 180 kilometers: - We can use the formula: time = distance / speed - Substituting the given values, we get: time = 180 / speed of motorcyclist

From Source we have: "60 minutes = 3 hours, 50 minutes = 5 hours"

This information can help us convert the time taken by the motorcyclist into hours.

2. Use the ratio of speeds to find the distance the bicyclist can travel in the same time: - We can use the ratio of speeds (4:1) to find the distance the bicyclist can travel in the same time as the motorcyclist.

3. Calculate the speed of the motorcyclist: - Using the distance the bicyclist can travel in the same time and the speed of the bicyclist, we can calculate the speed of the motorcyclist using the ratio of speeds.

Let's proceed with the calculations.
