The distance covered by an object is governed by the expression x3 + 3x2 + 2x. If the time taken to cover this distance is given by x + 1, what is the expression that governs the speed of the object?

x2+2x

x2+2x−1x+1

x+2

x2+1x+1

We know that distance = rate*time
They give you the factor of time. That means you need to find the rate.
You must divide the distance expression by the time expression to find the rate, or speed.

nathalyn · Answer

Distance = Rate * Time

Rate = Distance / Time

Give it a go.
