Question

Турист в первый день прошел 27 км за 6 ч во второй 16 км за 3 в третий 19 км за 5 в четвёртый 23 км за 5 какова средняя скорасть движения туриста на всём пройденом пути

Answer 1

1) 27:6=4,5 км/ч - скорость в первый день
2) 16:3=5,3 км/ч - скорость во второй день
3) 19:5=3,8 км/ч - скорость в третий день
4) 23:5=4,6 км/ч - скорость в четвертый день
5) (4,5+5,3+3,8+4,6):4=4,55 км/ч - средняя скорость
Ответ: 4,55 км/ч.

Answer 2

Calculation of Average Speed

To calculate the average speed of the tourist over the entire distance covered, we need to find the total distance traveled and the total time taken.

The tourist covered the following distances in each day: - First day: 27 km - Second day: 16 km - Third day: 19 km - Fourth day: 23 km

The total distance covered is the sum of these distances: 27 km + 16 km + 19 km + 23 km = 85 km.

The total time taken is the sum of the time taken on each day: - First day: 6 hours - Second day: 3 hours - Third day: 5 hours - Fourth day: 5 hours

The total time taken is 6 hours + 3 hours + 5 hours + 5 hours = 19 hours.

To calculate the average speed, we divide the total distance by the total time: 85 km / 19 hours = 4.47 km/h.

Therefore, the average speed of the tourist over the entire distance covered is approximately 4.47 km/h.
