Question

Велосипедист и пешеход находились в пути 20 минут.Велосипедист всё это время ехал со скоростью 280м/мин, а пешеход шёл со скоростью 80м/мин. На сколько больше расстояние проехал за это время велосипедист?

Answer 1

Велосипедист проехал 280 * 20 = 5600м, а пешеход прошел 80 * 20 = 1600м. Узнаем, насколько большее расстояние проехал пешеход, чем велосипедист: 5600 - 1600 = 4000м.
Ответ: На 4000м.

Answer 2

Answer in detail. The cyclist and the pedestrian were on the road for 20 minutes. The cyclist was riding at a speed of 280m/min, and the pedestrian was walking at a speed of 80m/min. How much longer did the cyclist travel than the pedestrian during this time?

To answer this question, we need to find the distance traveled by each person and then compare them. The distance traveled by a person is equal to the product of their speed and time. Therefore, we can use the following formula:

$$d = s \times t$$

where $d$ is the distance, $s$ is the speed, and $t$ is the time.

Using this formula, we can calculate the distance traveled by the cyclist and the pedestrian as follows:

- The cyclist traveled $d_c = 280 \times 20 = 5600$ meters. - The pedestrian traveled $d_p = 80 \times 20 = 1600$ meters.

The difference between the distances traveled by the cyclist and the pedestrian is:

$$d_c - d_p = 5600 - 1600 = 4000$$

Therefore, the cyclist traveled 4000 meters more than the pedestrian during this time.
