Question

ГОНОЧНЫЙ АВТОМОБИЛЬ ЗА 10 МИНУТ ПРОЕЗЖАЕТ ПУТЬ,РАВНЫЙ 109,2 КМ.ОПРЕДЕЛИТЕ ЕГО СРЕДНЮЮ СКОРОСТЬ.

Answer 1

T = 10 мин = 1/6 ч.
S = 109,2 км

V = S/t =109,2 / (1/6) = 109,2 * 6 км/ч. = 655,2 км/ч.

Answer 2

10 минут-это 1/6 часа.
Скорость вычисляется по формуле путь/время=> S=109.2/(1/6)=655.2 км/ч

Answer 3

Calculation of Average Speed

To calculate the average speed of a race car that travels a distance of 109.2 km in 10 minutes, we can use the formula:

Average Speed = Distance / Time

Given that the distance is 109.2 km and the time is 10 minutes, we can substitute these values into the formula:

Average Speed = 109.2 km / 10 min

To find the average speed, we need to convert the time from minutes to hours, as the distance is given in kilometers. There are 60 minutes in an hour, so we divide the time by 60:

Average Speed = 109.2 km / (10 min / 60 min/h)

Simplifying the equation:

Average Speed = 109.2 km / (10/60) h

Average Speed = 109.2 km / (1/6) h

To divide by a fraction, we can multiply by its reciprocal:

Average Speed = 109.2 km * (6/1) h

Average Speed = 655.2 km/h

Therefore, the average speed of the race car is 655.2 km/h.
