Question

Ученик решил 12 уравнений за 40 минут.Сколько минут он решал в среднем каждое уравнение?Сколько секунд он потратил на решение каждого уравнения?

Answer 1

40/12=10/3=3 1/3 мин-за столько решал в среднем каждое уравнение
10/3*60=10*20=200сек

Answer 2

Average Time to Solve Each Equation

To find the average time the student spent solving each equation, we can divide the total time spent by the number of equations. In this case, the student solved 12 equations in 40 minutes. Therefore, the average time spent on each equation can be calculated as:

Average time per equation = Total time / Number of equations Average time per equation = 40 minutes / 12 equations Average time per equation = 3.33 minutes per equation

Time Spent on Each Equation in Seconds

To find the time spent on each equation in seconds, we can convert the average time per equation from minutes to seconds. Since 1 minute is equal to 60 seconds, the time spent on each equation in seconds can be calculated as:

Time spent on each equation (in seconds) = Average time per equation * 60 Time spent on each equation (in seconds) = 3.33 minutes * 60 Time spent on each equation (in seconds) = 200 seconds

Therefore, the student spent an average of 3.33 minutes on each equation and 200 seconds on solving each equation.
