Your friend just challenged you to a race. You know in order to beat him, you must run 15 meters within 20 seconds in a northern direction. What does your average velocity need to be to win the race
Average Velocity = Distance/Time
So!
15m/20s
Reduce the fraction by 5 to yield the following result:
3m/4s
Or if you want it as a decimal...:
0.75m/s
Answer: Average velocity of him is 0.75 m/sec to win the race.
Step-by-step explanation:
Since we have given that
Distance he ran to beat him = 15 meters
Time he takes in a northern direction = 20 seconds
We need to find the average velocity need to be to win the race .
As we know that the velocity is the speed of particular object in a given direction.
So, the formula for average velocity is given by
\(Velocity=\frac{Distance}{time}\\\\Velocity=\frac{15}{20}=0.75\ m/sec\)
Hence, average velocity of him is 0.75 m/sec to win the race.
