Question 5 A person calculates the average speed of a car as 500 miles per hour on a family trip.

What could be a possible error in the person's reasoning?

A
The amount of time traveled reported was too high.

B
The distance traveled reported was too high.

C
The incorrect units for time was used.

D
The incorrect units for distance was used.

The distance traveled reported too high.

It has SI units m/s

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
