Question

Из одного пункта одновременно по одной и той же дороге в одну и ьу же сторону выехали два ведосипедиста.Они ехали с постоянными скоростями.Скорость первого велосипедиста 14 км/ч.Через час расст. между ними сатло 4 км.Какой могла бы быть скорость второго велосипедиста? Срочно!!!Помогите пожалуйста!

Answer 1

14 * 1 - х * 1 = 4
х = 14 * 1 - 4
х = 10 км/ч скорость второго велосипедиста

Answer 2

Problem Analysis

The problem describes two cyclists traveling at constant speeds along the same road in the same direction. The first cyclist's speed is given, and the distance between the two cyclists after one hour is also provided. We need to determine the speed of the second cyclist.

Solution

To solve this problem, we can use the formula:

Speed = Distance / Time

We know the speed of the first cyclist and the time that has passed. We can use this information to calculate the distance traveled by the first cyclist. Then, we can use the distance and the time to find the speed of the second cyclist.

Calculation

1. Calculate the distance traveled by the first cyclist: - Speed of the first cyclist = 14 km/h - Time = 1 hour - Distance = Speed * Time = 14 km/h * 1 h = 14 km

2. Calculate the speed of the second cyclist: - Distance between the cyclists after one hour = 4 km - Total distance traveled by the second cyclist = Distance traveled by the first cyclist + Distance between the cyclists after one hour = 14 km + 4 km = 18 km - Time = 1 hour - Speed of the second cyclist = Total distance / Time = 18 km / 1 h = 18 km/h

Answer

The speed of the second cyclist could be 18 km/h.
