Question

Электричка за три часа проехала 145км. Сколько километров она проежала за каждый из этих часов, если за первые два часа она проехала 98км, а за третий час на 3 меньше, чем за второй?

Answer 1

В 3 час она проехала 145-98=47 км
во второй час на 3 меньше,значит во второй час 47+3=50
в 1 час проехала 145-47-50=48 часов

Answer 2

Calculation of Distance Traveled per Hour

To calculate the distance traveled per hour, we need to divide the total distance traveled by the total number of hours. In this case, the total distance traveled is 145 km and the total time is 3 hours.

Therefore, the distance traveled per hour is 145 km / 3 hours = 48.33 km/h.

Distance Traveled for Each Hour

Now let's calculate the distance traveled for each of the three hours.

- For the first two hours, the train traveled 98 km. - For the third hour, the train traveled 3 km less than the second hour.

To find the distance traveled for the third hour, we subtract 3 km from the distance traveled in the second hour.

- Distance traveled for the third hour = Distance traveled in the second hour - 3 km

Let's calculate the distance traveled for the third hour:

- Distance traveled for the third hour = 98 km - 3 km = 95 km.

Therefore, the train traveled 98 km for the first two hours and 95 km for the third hour.

Summary

To summarize, the train traveled 145 km in total over a period of 3 hours. It traveled 98 km for the first two hours and 95 km for the third hour.
