Would metric time work? I know there is 60 seconds to a minute and 60 minutes to an hour and so on, but the actual length of a second, minute, hour had no definition till humans gave it one. The only problem i see is the number of Metric hours in a day, days in a month, number of months and the number of days in a year. If we are going to go the the metric system, we should go all the way. Not just whatever is most convenient.

Solve the following system of linear equations by the addition method. If there is no solution or an infinite number of solutions, so state. Check your answer.
4x + 3y = 12
2x – 4y = 6


so far:
x=3(-y+4)/4
y=4(-x+3)/3

am I close yet?

A particle is moving so that at time t, the distance is given by the function:

s(t) = -1/3(t)^3 - 5/2(t)^2 + 6(t)

At what time t greater than zero is the speed equal to zero

A man is running in a straight line. The distance (in meters) he has travelled from home is described by the equation.

s(t) = 8t^2 + 7t + 5

t is time in minutes. Find the average velocity of the man over the time interval (2.5, 3.5)

And for part B What is the instantaneous velocity at t=2
