Question

Помогити плис Задача: Растояние между двумя сёлами равно 156,3км. Из этих сёл одновременно в одном направлении выехали грузовик и велосипидист, причём велосипедист ехал впереди. Через 3 ч после начала движения грузовик догнал велосипедиста. Какой была скорость велосипедиста, если скорость грузовика 64,5 км/ч

Answer 1

1. 64,5 км/ч *3 ч= 193,5 км
2.193,5 км-156,3 км= 37,2 км
3.37,2 км : 3 ч= 12,4 км/ч - это скорость велосипедиста

Answer 2

Problem Analysis

We are given that the distance between two villages is 156.3 km. A truck and a cyclist start simultaneously from one of the villages, with the cyclist in front. After 3 hours of travel, the truck catches up to the cyclist. We need to determine the speed of the cyclist, given that the speed of the truck is 64.5 km/h.

Solution

To solve this problem, we can use the formula:

Distance = Speed × Time

Let's assume the speed of the cyclist is v km/h. Since both the truck and the cyclist travel for 3 hours, we can set up the following equation:

156.3 km = (v km/h) × 3 hours

Simplifying the equation, we have:

156.3 km = 3v km

Now, we can solve for v by dividing both sides of the equation by 3:

v km/h = 156.3 km / 3

Evaluating the right side of the equation, we find:

v km/h ≈ 52.1 km/h

Therefore, the speed of the cyclist was approximately 52.1 km/h.

Answer

The speed of the cyclist was approximately 52.1 km/h.
