Question

A vehicle travels a distance of 5t4 − 10t2 + 6 miles in t + 2 minutes.

The vehicle's speed is __________miles/minute.

Answer 1

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

Answer 2

Speed of the vehicle=
`(5t^(4)-10t^(2)+6)/(t+2)miles/min`

Explanation:

Given that,

Distance traveled by the vehicle = 5t⁴ - 10t² + 6 miles

time = t + 2 minutes

We need to find the speed of vehicle. Use the formula of speed is:

`Speed=(Dstance)/(Tme)`

`Speed=(5t^(4)-10t^(2)+6)/(t+2)`

So, speed of the vehicle=
`(5t^(4)-10t^(2)+6)/(t+2)`

That's the final answer.
