Question

Срочно осталось пять минут!!!!! За час спортивного бега со скоростью 2,5 м/с подросток сжигает около 500 калорий. Как далеко надо убежать от кафе быстрого питания, после употребления молочного коктейля (240 000 калорий), чтобы эти калории израсходовать. И сколько времени на это необходимо? Ответ дайте в часах и километрах.

Answer 1

Ответ:

Пошаговое объяснение:

1) 240000:500=480 часов бега понадобится (если коктейль реально 240 000 и тут нет ошибки)

2) 2,5*60*60=9000 м/ч скорость бега

3) 9000:1000=9 км/ч скорость бега

4) 480*9=4320 км понадобится пробежать

Answer 2

Calculation of Distance and Time Required to Burn Calories

To calculate the distance and time required to burn the calories consumed from a milkshake at a fast-food restaurant, we need to consider the number of calories burned per hour of running and the number of calories in the milkshake.

According to the information provided, a teenager burns approximately 500 calories in one hour of running at a speed of 2.5 m/s The milkshake consumed contains 240,000 calories.

To calculate the distance, we can use the formula:

Distance = Speed × Time

Let's calculate the time required to burn the calories and then use it to calculate the distance.

1. Calculation of Time Required: - Calories in the milkshake: 240,000 calories - Calories burned per hour: 500 calories - Time required to burn the calories: 240,000 calories / 500 calories per hour = 480 hours

2. Calculation of Distance: - Speed: 2.5 m/s - Time: 480 hours (converted to seconds: 480 hours × 3600 seconds/hour = 1,728,000 seconds) - Distance = Speed × Time = 2.5 m/s × 1,728,000 seconds = 4,320,000 meters

Therefore, to burn the calories consumed from the milkshake, the teenager would need to run approximately 4,320,000 meters, which is equivalent to 4,320 kilometers. This would require approximately 480 hours of running.

Please note that these calculations are based on the information provided and may vary depending on individual factors such as metabolism and fitness level.
