The following data were taken on five cars traversing a 1.6-km highway. Car Time (minutes) A 1.9 B 1.2 C 1.8 D 1.1 E 1.9 Determine the traffic density, in vehicles per km. Express your answer in 2 decimal places.
A car starts from 2.0 m/s and accelerates at 4.0 m/s for 6.0 s, it then coasts for 5.0 s. How far has it traveled, in meters? Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
A runner travels 50 m over a duration of 12.6 s. She took 29 steps over the 50 m. What was her average step rate in steps/s? Report to two decimal points (e.g. 1.23). You are allowed a margin of error of +/- 0.02.
A runner wants to run 12.2 kmkm . She knows that her running pace is 6.8 mi/hmi/h . How many minutes must she run? Hint: Use 6.8 mi/hmi/h as a conversion factor between distance and time. Express your answer using two significant figures.
If it takes a horse 175 seconds to make 3.00 laps around a horse track (each lap is equal to 1.00 km), what was the horse's average velocity in m/s when he crosses the start/finish line? Be sure to answer to the correct number of significant digits and include units.
QUESTION 6 Supply all missing information with the correct numerical values. Do not include the units. Round off all answers to two decimal places. Do not forget the negative sign (-) if needed. Pedro is driving a motorcycle along Espana boulevard. His position X (in meters) at any given time t is given by x(t) =1.124t + 6.022. Pedro's initial position is X= m. His position at ten seconds is X= m. His speed at ten seconds is V= m/s. His acceleration at ten seconds is a = m/s2. Marites is also driving her motorcycle along Espana. Her position function is of the form x(t) = Ct. What is the coefficient C if her acceleration at ten seconds is 2.04 m/s? C = m/s4

I took 2.28km and converted it to 2280 meters then divided by 3200 and ended up with .71m/s but it keeps saying that its incorrect. Im not sure where I keep messing up. John walks 1.80 kmkm north, then turns right and walks 1.40 kmkm east. His speed is 1.60 m/sm/sduring the entire stroll. What is the magnitude of his displacement, from beginning to end? (2.28) If Jane starts at the same time and place as John, but walks in a straight line to the endpoint of John's stroll, at what speed should she walk if she wants to arrive at the endpoint just when John does?
