Question

Two vehicles are traveling at constant speeds. The distance traveled over a period of

time by the first vehicle is shown in the graph below. The distance traveled over a
period of time by the second vehicle is shown in the table below. Which vehicle is traveling
at a greater speed?
Vehicle 1
Vehicle 2
Distance (miles)
(3,120)
(2,80)

Answer 1

Vehicle 1 is Moving Faster.

Explanation:

For vehicle 1.

(2,80) (3,120)

∆Distance= 120-80 = 40miles

∆time = 3-2=1hr

So V=Distance/time = 40miles/1hr

V1 = 40miles per hour.

For car 2.

∆Distance=240-150 =90miles

∆time=8-5 = 3hrs

V=90/3

V=30Miles per hour.

So Car1 is Moving faster and at a velocity of 40Miles per hour.

Answer 2

Explanation:

vehicle one is traveling at a greater speed. from the graphs we can see that in one hour the care would travel 40 miles.

the table shows the 2nd vehicle traveling 30 miles in one hour

So car 1 is going faster :)
