Question

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

Answer 1

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 2

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.
