Question

Турист проехал на автомобиле 8 ч.со скоростью 74км/ч,а остальную часть пути он преодолел на велосипеде со скоростью 12 км/ч.сколько времени путешествовал турист,если всего он преодолел путь в 612 км?

Answer 1

1) 74 * 8 = 592 (км) проехал турист на автомобиле
2) 612 - 592 = 20 (км) проехал турист на велосипеде
3) 20 : 12 = 1 2/3 (ч) = 1ч 40мин. турист ехал на велосипеде
4) 8ч + 1ч40мин = 9ч 40мин.
Ответ: 9 ч 40 мин. - время, затраченное на весь путь.

Answer 2

Calculation of Travel Time

To calculate the total travel time of the tourist, we need to determine the time spent traveling by car and the time spent traveling by bicycle.

Let's start by calculating the time spent traveling by car. The tourist traveled for 8 hours at a speed of 74 km/h. We can use the formula:

Time = Distance / Speed

The distance traveled by car can be calculated by subtracting the distance traveled by bicycle from the total distance of 612 km:

Distance by car = Total distance - Distance by bicycle

Distance by car = 612 km - Distance by bicycle

Now, let's calculate the distance traveled by bicycle. The speed of the bicycle is given as 12 km/h. We can use the formula:

Distance = Speed * Time

Let's substitute the values into the formulas and calculate the time spent traveling by car and bicycle.

Distance by bicycle = Speed by bicycle * Time by bicycle

Distance by car = 612 km - Distance by bicycle

Since we don't have the exact values for the distance traveled by bicycle and the time spent traveling by bicycle, we cannot provide an exact answer at this time. However, you can use the formulas provided above to calculate the time spent traveling by the tourist once you have the distance traveled by bicycle.
