Holden is trying to determine the velocity of his race car. He went 20 meters east, turned around, and went 40 meters west. He turned the car one more time and went 35 meters east. His car was 15 meters from the starting line. This took 5 seconds. What is the car's velocity?

The velocity of Holden's race car is 3m/s

Step-by-step explanation:

Velocity =Displacement/Time

Displacement=Final Position - Initial Position

Now, although e went 20 meters east, turned around, and went 40 meters west. He also turned the car one more time and went 35 meters east.

We are not looking for the distance travelled, we only require his displacement.

Holden's car is 15 metres from his starting line, so his displacement =15m

Time taken =5 seconds

Velocity of the Race Car

=15/5 = 3m/s

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

x-3y=4
