Question

Два велосипедистов выехали одновременно навстречу друг другу первый ехал со скоростью 15км/ч а второй проехал до встречи на 6 км больше чем первый С какой скоростью ехал второй велосипедист если он встретился с первым через 3 часа

Answer 1

1 15*3= 45 км проехал 1 велосепидист
2 45+6=51км расстояние 2 велосепидиста
3 51:3=17 км\ч скорость 2 велосепидиста

Answer 2

Problem Analysis

Two cyclists are traveling towards each other. The first cyclist is traveling at a speed of 15 km/h, while the second cyclist travels 6 km further before meeting the first cyclist. We need to determine the speed at which the second cyclist is traveling if they meet the first cyclist after 3 hours.

Solution

Let's break down the problem step by step:

1. Calculate the distance traveled by the first cyclist in 3 hours. 2. Calculate the distance traveled by the second cyclist in 3 hours. 3. Determine the speed of the second cyclist.

Step 1: Calculate the distance traveled by the first cyclist in 3 hours

The distance traveled by an object can be calculated using the formula: distance = speed × time.

Given that the first cyclist is traveling at a speed of 15 km/h and the time is 3 hours, we can calculate the distance traveled by the first cyclist as follows:

Distance traveled by the first cyclist = Speed of the first cyclist × Time = 15 km/h × 3 hours = 45 km.

Step 2: Calculate the distance traveled by the second cyclist in 3 hours

We know that the second cyclist travels 6 km further than the first cyclist before meeting. Therefore, the distance traveled by the second cyclist is the distance traveled by the first cyclist plus the additional 6 km.

Distance traveled by the second cyclist = Distance traveled by the first cyclist + 6 km = 45 km + 6 km = 51 km.

Step 3: Determine the speed of the second cyclist

To determine the speed of the second cyclist, we need to divide the distance traveled by the second cyclist by the time taken, which is 3 hours.

Speed of the second cyclist = Distance traveled by the second cyclist ÷ Time = 51 km ÷ 3 hours = 17 km/h.

Therefore, the second cyclist is traveling at a speed of 17 km/h.

Answer

The second cyclist is traveling at a speed of 17 km/h.
