Question

Из села в город выехал мотоциклист со скоростью 53 км/ч. В то же время из города в это село выехал велосипедист со скоростью 18 км/ч. Какое расстояние будет между ними через 3 часа, если расстоянии от города до села 220 км/ч?

Answer 1

53*3=159 км проехал мотоциклист

18*3=54 проехал велосипедист

220-(159+54)=7 км - расстояние между ними

Answer 2

Problem Analysis

We are given the following information: - A motorcyclist travels from a village to a city at a speed of 53 km/h. - At the same time, a cyclist travels from the city to the village at a speed of 18 km/h. - The distance between the city and the village is 220 km. - We need to find the distance between them after 3 hours.

Calculation

To find the distance between the motorcyclist and the cyclist after 3 hours, we need to calculate the distances each of them has traveled.

The distance traveled by the motorcyclist can be calculated using the formula: Distance = Speed × Time

Substituting the given values: Distance traveled by the motorcyclist = 53 km/h × 3 hours

Similarly, the distance traveled by the cyclist can be calculated using the same formula: Distance traveled by the cyclist = 18 km/h × 3 hours

To find the distance between them, we subtract the distance traveled by the cyclist from the distance traveled by the motorcyclist: Distance between them = Distance traveled by the motorcyclist - Distance traveled by the cyclist

Calculation Steps

1. Calculate the distance traveled by the motorcyclist: - Speed of the motorcyclist = 53 km/h - Time = 3 hours - Distance traveled by the motorcyclist = 53 km/h × 3 hours

2. Calculate the distance traveled by the cyclist: - Speed of the cyclist = 18 km/h - Time = 3 hours - Distance traveled by the cyclist = 18 km/h × 3 hours

3. Calculate the distance between them: - Distance between them = Distance traveled by the motorcyclist - Distance traveled by the cyclist

Calculation Results

1. Distance traveled by the motorcyclist = 53 km/h × 3 hours = 159 km 2. Distance traveled by the cyclist = 18 km/h × 3 hours =#### Calculating the Distance Between the Motorcyclist and the Cyclist

To calculate the distance between the motorcyclist and the cyclist after 3 hours, we can use the formula:

Distance = Speed × Time

Given: - Motorcyclist's speed = 53 km/h - Cyclist's speed = 18 km/h - Time = 3 hours

Using the formula, we can calculate the distances traveled by the motorcyclist and the cyclist after 3 hours.

The distance traveled by the motorcyclist after 3 hours is: Distance_motorcyclist = Speed_motorcyclist × Time Distance_motorcyclist = 53 km/h × 3 h Distance_motorcyclist = 159 km The distance traveled by the cyclist after 3 hours is: Distance_cyclist = Speed_cyclist × Time Distance_cyclist = 18 km/h × 3 h Distance_cyclist = 54 km

Calculating the Distance Between the Motorcyclist and the Cyclist

The distance between the motorcyclist and the cyclist after 3 hours can be calculated by finding the difference between the distances traveled by the motorcyclist and the cyclist.

Distance_between = Distance_motorcyclist - Distance_cyclist Distance_between = 159 km - 54 km Distance_between = 105 km

Therefore, the distance between the motorcyclist and the cyclist after 3 hours, given a distance of 220 km from the city to the village, is 105 km.
