Question

Из пунктов А и В, расстояние между которыми 260 км, одновременно на встречу друг друга выехали велосипедист и мотоциклист.Скорость велосипедиста - 13 км/ч, а мотоциклиста - 52 км/ч. Запешите в виде выражения: 1) на сколько скорость велосипедиста меньше скорости мотоциклиста. 2) во сколько раз скорость велосипедиста меньше скорости мотоциклиста. 3)время, которое потребуется велосипедисту на весь путь из А и В. 4)время,которое потребуется велосипедисту на весь путь из В в А 5) на сколько меньше времени потребуется на весь путь мотоциклисту, чем велосипедисту; 6) во сколько раз меньше времени потребуется на весь путь мотоциклисту<чем велосипедисту; 7) скорость сблежения велосипедиста и мотоциклиста 8) через какое время после начала движения велосипедист и мотоциклист встретятся

Answer 1

1) 52-19
2) 52/19
3) 260/13
4) 260/52
5) (260/52)-(260/13)
6) (260/52)/(260/13)
7) 52+13
8) 260/(52+13)

Answer 2

Given Information:

- Distance between points A and B: 260 km - Speed of the cyclist: 13 km/h - Speed of the motorcyclist: 52 km/h

Calculations:

1) The difference in speed between the cyclist and the motorcyclist can be calculated by subtracting the speed of the cyclist from the speed of the motorcyclist: 52 km/h - 13 km/h = 39 km/h. 2) The ratio of the cyclist's speed to the motorcyclist's speed can be calculated by dividing the speed of the cyclist by the speed of the motorcyclist: 13 km/h ÷ 52 km/h = 0.25. 3) The time it will take for the cyclist to travel the entire distance from A to B can be calculated by dividing the distance by the speed of the cyclist: 260 km ÷ 13 km/h = 20 hours. 4) The time it will take for the cyclist to travel the entire distance from B to A will also be 20 hours, as the distance is the same and the speed of the cyclist remains constant. 5) The difference in time it will take for the motorcyclist to travel the entire distance compared to the cyclist can be calculated by subtracting the time it will take for the cyclist to travel the entire distance from the time it will take for the motorcyclist: 20 hours - 20 hours = 0 hours. 6) The ratio of the time it will take for the motorcyclist to travel the entire distance to the time it will take for the cyclist can be calculated by dividing the time it will take for the motorcyclist by the time it will take for the cyclist: 0 hours ÷ 20 hours = 0. 7) The closing speed of the cyclist and the motorcyclist can be calculated by adding their speeds together: 13 km/h + 52 km/h = 65 km/h. 8) The time it will take for the cyclist and the motorcyclist to meet can be calculated by dividing the distance between points A and B by their closing speed: 260 km ÷ 65 km/h = 4 hours.

Answers:

1) The speed of the cyclist is 39 km/h less than the speed of the motorcyclist. 2) The speed of the cyclist is 0.25 times less than the speed of the motorcyclist. 3) The time it will take for the cyclist to travel the entire distance from A to B is 20 hours. 4) The time it will take for the cyclist to travel the entire distance from B to A is also 20 hours. 5) The motorcyclist will take 0 hours less than the cyclist to travel the entire distance. 6) The motorcyclist will take 0 times less than the cyclist to travel the entire distance. 7) The closing speed of the cyclist and the motorcyclist is 65 km/h. 8) The cyclist and the motorcyclist will meet 4 hours after the start of their journey.
