you have the formula, so plug and chug
s = d/t = (3p^2+5p-2)/(3p^2+2p-1) = (3p-1)(p+2) / (3p-1)(p+1)
exclude values of p where the denominator is zero
Now reduce to get
s = (p+2)/(p+1)
Speed is determined by dividing the distance travelled by the time taken to travel the
distance or s= d/t. Write a rational expression for speed, given the distance travelled,
is 3p^2+5p-2 and the time to travel that distance is 3p^2+2p-1. Identify any nonpermissible values.
