Question

A) vehicle 1 is traveling at greater speed

B) vehicle 2 is traveling at a greater speed
C) vehicle 1 and 2 are traveling at the same speed
D) there is not enough information to determine which vehicle is traveling at a greater speed

Answer 1

Answer: A) vehicle 1 is traveling at greater speed

========================================================

Step-by-step explanation:

Let's find the slope of the graph

m = (y2-y1)/(x2-x1)

m = (120-80)/(3-2)

m = 40/1

m = 40

Each time x goes up by 1, y goes up by 40.

Vehicle 1 travels 40 miles for each hour, ie, its speed is 40 mph.

-------------

Now find the slope of the table

m = (y2-y1)/(x2-x1)

m = (240-150)/(8-5)

m = 90/3

m = 30

Vehicle 2's speed is 30 mph.

We see that Vehicle 1 is traveling 10 mph faster compared to Vehicle 2.
