Question

Из двух пунктов, расстояние между которыми 532 км,одновременно навстречу друг другу выехали два мотоциклиста. Через 5 часов расстояние между ними было 32 км. Вычислите скорость второго мотоциклиста , если скорость первого 45 км/чПж решите эту задачу

Answer 1

1) 10•3=30(км)-проехал велосипедист за 3часа.
2) 220-30-70=120(км)-проехал мотоциклист за 3часа.
3) 120:3=40(км/ч)- скорость мотоциклиста
Ответ: 40 км/ч

Answer 2

Problem Analysis

We have two motorcycles traveling towards each other from two different points. The distance between the two points is 532 km. After 5 hours, the distance between the motorcycles is 32 km. We need to calculate the speed of the second motorcycle, given that the speed of the first motorcycle is 45 km/h.

Solution

To solve this problem, we can use the formula: speed = distance / time.

Let's calculate the time it took for the motorcycles to cover the initial distance of 532 km. We can use the formula: time = distance / speed.

For the first motorcycle: - Distance = 532 km - Speed = 45 km/h - Time = 532 km / 45 km/h = 11.822 hours

Since the motorcycles started at the same time, the total time they traveled is the same. Therefore, the total time is 11.822 hours.

Now, let's calculate the speed of the second motorcycle. We can use the formula: speed = distance / time.

For the second motorcycle: - Distance = 532 km - 32 km = 500 km (the remaining distance after 5 hours) - Time = 11.822 hours - 5 hours = 6.822 hours

Now we can calculate the speed of the second motorcycle: - Speed = 500 km / 6.822 hours = 73.33 km/h

Answer

The speed of the second motorcycle is 73.33 km/h.

Explanation

The first motorcycle traveled at a speed of 45 km/h and took 11.822 hours to cover the initial distance of 532 km. The second motorcycle, which started at the same time, traveled a remaining distance of 500 km in 6.822 hours. Therefore, the speed of the second motorcycle is calculated to be 73.33 km/h.
