Answer:
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
