Respuesta :
The time taken by the race car to finish the race will be 8000 sec. The time taken is the ratio of the distance travelled and the velocity.
What is the average speed?
The total distance traveled by an object divided by the total time taken is the average speed.
The average speed of an object indicates the pace at which it will traverse a distance. The metric unit of speed is the meter per second.
The given data in the problem is;
Distance (d₁) = 640000 M
Time (t₁) = ?
V ( average speed)=80m/s
The average speed is found as;
[tex]\rm t = \frac{d}v} \\\\ t= \frac{640000}{80} \\\\ t= 8000 \ sec[/tex]
Hence, the time taken by the race car to finish the race will be 8000 sec.
