Question

геологи 8 3/4 часа ехали на автомобиле, 7 1/2 часа шли пешком. Все расстояние равно 225 км. найти скорость геологов на автомобиле и пешеом, если проехали они в 14 раз больше, чем прошли пешком

Answer 1

225/15=15 км прошли пешком

225-15=210 км проехали

Скорость пешком 15/7,5=2 км/ч

Скорость на автомобиле 210/8,75=24 км/ч

Answer 2

Calculating the Speed of Geologists

To calculate the speed of the geologists on the car and on foot, we can use the information provided in the question and apply the concept of time, distance, and speed.

Given: - Time traveled by car = 8 3/4 hours - Time traveled on foot = 7 1/2 hours - Total distance traveled = 225 km - The distance traveled by car is 14 times greater than the distance traveled on foot

Calculating the Speed of the Geologists by Car

To find the speed of the geologists traveling by car, we can use the formula: \[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]

The distance traveled by car can be represented as \(14x\), where \(x\) is the distance traveled on foot. Therefore, the distance traveled by car is \(14x\) and the distance traveled on foot is \(x\).

Given: - Time traveled by car = 8 3/4 hours - Distance traveled by car = 14x

Using the formula, we can calculate the speed of the geologists by car.

Calculating the Speed of the Geologists on Foot

To find the speed of the geologists traveling on foot, we can use the same formula: \[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]

Given: - Time traveled on foot = 7 1/2 hours - Distance traveled on foot = x

Using the formula, we can calculate the speed of the geologists on foot.

Conclusion

By using the given information and the concepts of time, distance, and speed, we can calculate the speed of the geologists traveling by car and on foot.

Let's calculate the speeds based on the given information.
