Question

Велосипедист проехал первую часть дистанции за 2 часа 20 минут,а вторую часть за 3 часа 40 мин найдите среднюю скорость велосипедиста(в м/мин),если его скорость на первом участке пути была 240 м/мин,а на втором-204м/мин

Answer 1

S1=240
S2=204
t-2ч.20мин=140мин
t-3ч.40мин=220мин
Vср=S/t=240+204 дробь 140+220=1.123м/мин

Answer 2

Calculation of Average Speed

To find the average speed of the cyclist, we can use the formula:

Average Speed = Total Distance / Total Time

Let's calculate the average speed step by step.

1. Calculate the total distance: - The cyclist traveled the first part of the distance in 2 hours and 20 minutes. - The cyclist traveled the second part of the distance in 3 hours and 40 minutes. - Since we don't have the actual distances for each part, we cannot calculate the total distance.

2. Calculate the total time: - The cyclist spent 2 hours and 20 minutes on the first part of the distance. - The cyclist spent 3 hours and 40 minutes on the second part of the distance. - We need to convert the time into minutes to have a consistent unit. - 2 hours and 20 minutes is equal to 2 * 60 + 20 = 140 minutes. - 3 hours and 40 minutes is equal to 3 * 60 + 40 = 220 minutes. - The total time is 140 + 220 = 360 minutes.

3. Calculate the average speed: - We need to divide the total distance by the total time, but since we don't have the total distance, we cannot calculate the average speed.

Unfortunately, without knowing the actual distances for each part of the distance, we cannot calculate the average speed of the cyclist.
