Question

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)

Please help and explain the answers please.

Answer 1

a is v=2t+50

for Part B you plug in o for t you get (0.50) and (6,62) connect those 2 points and you have your graph after the first 6 hours
