Question

Велосипедист за первые 5 с проехал 25м за следующие 10с 100м и за последние 10с 75 м найдите среднюю скорость велосипедиста на всем пути помогите срочно​

Answer 1

Ответ:

v (ср) = 8 м/с

Объяснение:

v (ср) = (S1+S2+S3)/(t1+t2+t3) = (25+100+75)/(5+10+10) = 200/25 = 8 м/с

Answer 2

Calculation of Average Speed

To find the average speed of the cyclist, we need to calculate the total distance traveled and the total time taken.

The cyclist traveled 25 meters in the first 5 seconds, 100 meters in the next 10 seconds, and 75 meters in the last 10 seconds. Therefore, the total distance traveled is 25 + 100 + 75 = 200 meters.

The total time taken is 5 + 10 + 10 = 25 seconds.

To calculate the average speed, we divide the total distance by the total time:

Average Speed = Total Distance / Total Time

Average Speed = 200 meters / 25 seconds

Average Speed = 8 meters per second

Therefore, the average speed of the cyclist over the entire distance is 8 meters per second.
