Question

Петя Зубов опять проспал в школу. До начала урока осталось 45 минут. Расстояние между Петиным домом и школой 4 км. Успеет ли Петя до начала урока, если он одевается 7 минут и бежит со скоростью 6 км/ч?

Answer 1

4 : 6 = 2/3 часа = 40 минут бежит Петя
40 + 7 = 47 минут надо Пете, чтобы одеться и добежать до школы
47 - 45 = 2 минуты - опоздание. 
Ответ: за 45 минут Петя не успеет одеться и добежать до школы, он опоздает на 2 минуты 

Answer 2

45-7=32
4/6=2/3 часа
2/3 от часа это 40 мин  то есть не успееет

Answer 3

Calculating if Petya Will Make It to School on Time

Petya needs to determine if he can make it to school on time, given that he has overslept and has 45 minutes until the start of the lesson. The distance between Petya's house and the school is 4 km, and he takes 7 minutes to get dressed. Petya runs to school at a speed of 6 km/h.

To calculate if Petya will make it to school on time, we can use the following formula:

Time = Distance / Speed

First, we need to convert Petya's running speed from km/h to km/min to match the time unit.

6 km/h = 6 km / 60 min = 0.1 km/min

Now, we can calculate the time it will take Petya to run to school:

Time taken to run to school = Distance / Speed = 4 km / 0.1 km/min = 40 min

Adding the time it takes Petya to get dressed (7 minutes) to the time it takes him to run to school (40 minutes), we get:

Total time = 7 min (dressing) + 40 min (running) = 47 min

Since the total time required is 47 minutes, which exceeds the 45 minutes Petya has until the start of the lesson, Petya will not make it to school on time.
