(350-126)/(5-3)=112m/s

This is the average speed in the time from 3 to 5 seconds...

dd/dt    98,126,154
d2d/dt2   28,28

She actually had a constant acceleration over the entire time period.

The function for that table is:

d(t)=14t^2  

Her actual velocity at any point is v(t)=28t  (you can see that if you take the mid point of the interval, 4s, you will get the average velocity found earlier)

The formula that shows the relationship between the distance, rate and time is t = d/r and t = 5.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

An independent variable is a variable that does not depend on any other variable for its value while a dependent variable is a variable that depends on other variable.

Given that:

d = rt

Hence:

t = d/r

For d = 40, r = 8:

t = 40 / 8

t = 5

The formula that shows the relationship between the distance, rate and time is t = d/r and t = 5.
