Question

ПОМОГИТЕ ПОЖАЛУЙСТА РЕШИТЬ . Турист 2 часа ехал на велосипеде, а потом 3 часа шел пешком.Он шел со скоростью 5км/ч, а на велосипеде ехал быстрее на 7 км/ч.Верно ли утверждение? 1. ПЕШКОМ ТУРИСТ ПРОШЕЛ 15 КМ. 2.ВЕСЬ ПУТЬ ТУРИСТА СОСТАВИЛ 29 КМ.

Answer 1

1. 3×5=15 км прошел турист пешком
2. 5+7=12 км/ч скорость туриста на велосипеде
     12×2=24 км турист проехал на велосипеде
     24+15=39 км весь путь туриста
     

Answer 2

5*3=15
7+5*2=24
Про весь путь легко

Answer 3

Problem Analysis

The problem states that a tourist traveled on a bicycle for 2 hours and then walked for 3 hours. The tourist walked at a speed of 5 km/h, while the bicycle speed was 7 km/h faster. The problem asks if the following statements are true: 1. The distance the tourist walked on foot is 15 km. 2. The total distance traveled by the tourist is 29 km.

Solution

To solve this problem, we need to calculate the distance traveled by the tourist on foot and the total distance traveled.

Let's start by calculating the distance traveled on foot. We know that the tourist walked for 3 hours at a speed of 5 km/h. Therefore, the distance traveled on foot can be calculated as follows:

Distance walked on foot = Speed × Time

Distance walked on foot = 5 km/h × 3 hours

Distance walked on foot = 15 km

So, the first statement is true. The distance the tourist walked on foot is indeed 15 km.

Next, let's calculate the total distance traveled by the tourist. We know that the tourist traveled on a bicycle for 2 hours at a speed that is 7 km/h faster than the walking speed. Therefore, the bicycle speed can be calculated as follows:

Bicycle speed = Walking speed + 7 km/h

Bicycle speed = 5 km/h + 7 km/h

Bicycle speed = 12 km/h

Now, we can calculate the distance traveled on the bicycle:

Distance traveled on the bicycle = Bicycle speed × Time

Distance traveled on the bicycle = 12 km/h × 2 hours

Distance traveled on the bicycle = 24 km

Finally, we can calculate the total distance traveled by adding the distance walked on foot and the distance traveled on the bicycle:

Total distance traveled = Distance walked on foot + Distance traveled on the bicycle

Total distance traveled = 15 km + 24 km

Total distance traveled = 39 km

Therefore, the second statement is false. The total distance traveled by the tourist is 39 km, not 29 km.

To summarize: 1. The first statement is true. The distance the tourist walked on foot is 15 km. 2. The second statement is false. The total distance traveled by the tourist is 39 km, not 29 km.
