Sam is observing the velocity of a car at different times. After two hours, the velocity of the car is 54 km/h. After four hours, the velocity of the car is 58 km/h.

Part A: Write an equation in two variables in the standard form that can be used to describe the velocity of the car at different times. Show your work and define the variables used. (5 points)

Part B: How can you graph the equation obtained in Part A for the first six hours? (5 points)

anonymous · Answer

I have v=50+2t for part A

pawanyadav · Answer

No
That's not correct

pawanyadav · Answer

Find  a  from above equation.

pawanyadav · Answer

Sorry I wrongly typed that 
It should be 
   58=54 +a(4)
As time is 4 hours

pawanyadav · Answer

If you got that 
I start the next part

pawanyadav · Answer

From there a=1
So equation should be 
     v=54+1(t)
Where v is velocity
And t is time.
