Question

(50pts) The distance covered and the time taken by a car are plotted in a graph.

a. Find the slope of the line in the graph.
b. Calculate the distance traveled by the car at the 20th second.
c. Calculate the speed of the car.

Answer 1

a=2

b=40m

c=2m/s

Explanation:

slope is rise over run so 10/5 simplified is 2/1 or 2

for b just look at the graph at the 20th second

for c you do distance over time so basically the same thing as a 10/5 which is 2m/s
