Question

В 8 30 утра из села в город выехала машина со скоростью 90 км/ч и в 12 30 приехала к месту назначения. Сколько километров проехал автомобиль если в пути он сделал две остановки по 15 мин?

Answer 1

15 * 2 = 30 мин.

12 ч. 30мин.-8 ч.30 мин.-30мин=3 ч. 30 мин.

3ч.30.мин. = 3.5 ч.

90*3ю5 = 315км.

 

Answer 2

15*2=30мин

12ч30мин-8ч30мин-30мин=3ч30мин

3ч30мин=3,5ч

90*3,5=315км

Answer 3

Calculation of the Distance Traveled by the Car

To calculate the distance traveled by the car, we need to determine the total time it took for the car to reach its destination, including the time spent on two stops of 15 minutes each.

Given: - The car left the village at 8:30 AM. - The car arrived at its destination at 12:30 PM. - The car made two stops of 15 minutes each.

To calculate the total time of the journey, we can subtract the time spent on the stops from the total time elapsed between the departure and arrival:

Total time of the journey = Time of arrival - Time of departure - Time spent on stops

Let's calculate the total time of the journey:

Time of departure: 8:30 AM Time of arrival: 12:30 PM

Converting the time to a 24-hour format: Time of departure: 8:30 Time of arrival: 12:30

Calculating the total time of the journey: Total time of the journey = 12:30 - 8:30 - (2 stops * 15 minutes)

To subtract the time spent on the stops, we need to convert the stops' duration from minutes to hours. Each stop lasted 15 minutes, which is equivalent to 15/60 = 0.25 hours.

Total time of the journey = 12:30 - 8:30 - (2 * 0.25)

Now, let's calculate the distance traveled by the car using the formula:

Distance = Speed * Time

Given: - Speed of the car = 90 km/h - Total time of the journey = calculated above

Distance = 90 km/h * Total time of the journey

Let's calculate the distance traveled by the car.
