Question

I need help understand how they got the solution/y for t.

Answer 1

Step-by-step explanation

As the average velocity equation is:

`v_(ave)=(s(t)-s(a))/(t-a)`

And as a=2, by plugging in the different values of t, from greater to smaller the function tends to 12, because the limit is 12.

For example, when t=2.1, the value of s(t) should be 11.23, as shown as follows:

`12.300000=(s(t)-10)/(2.1-2)`

Isolating s(t):

`12.300000(2.1-2)=s(t)-10`
`12.300000\cdot0.1=s(t)-10`
`1.23=s(t)-10`
`1.23+10=s(t)`
`11.23=s(t)`
