Question

A vehicle travels a distance of 5t4 − 10t2 + 6 miles in t + 2 minutes. What is the vehicle's speed?

Answer 1

The speed is 5t^3 - 10t^2 + 10t - 20 + 46/(t+2) miles per minute

Explanation:

Answer 2

Let distance be s and velocity be v
s = 5t⁴ - 10t² + 6
We know velocity is the change in distance per unit time, so
v = ds/dt
v = 20t³ - 20t
