Question

кАТЕР ЗА 2 часа прошёл 80 км.Чему равна его скорость,выраженная в метрах в минуту?

Answer 1

80:2=40 км/ч

(40*1000):60=666,6666666666667м/м

Ответ:666,6 метров в минуту                                                                 

Answer 2

Calculation of Speed

To calculate the speed of the boat, we need to divide the distance traveled by the time taken. In this case, the boat traveled 80 km in 2 hours. To express the speed in meters per minute, we need to convert both the distance and time to meters and minutes, respectively.

1 kilometer (km) is equal to 1000 meters (m), and 1 hour is equal to 60 minutes. Therefore, we can convert the distance of 80 km to meters by multiplying it by 1000, and the time of 2 hours to minutes by multiplying it by 60.

Let's perform the calculations:

Distance in meters = 80 km * 1000 m/km = 80,000 m Time in minutes = 2 hours * 60 min/hour = 120 min

Now, we can calculate the speed:

Speed = Distance / Time = 80,000 m / 120 min

To find the speed in meters per minute, we divide the distance by the time:

Speed = 666.67 m/min

Therefore, the speed of the boat, expressed in meters per minute, is approximately 666.67 m/min.
