What is the average speed of an object if it has travelled a total distance of 6.00km in 20.0s?

1080 km/hr or 300 m/s

Explanation:

Given:

Distance = S = 6 km = 6000 m

Time = t = 20 s

Required:

Average Speed = v = ?

Formula:

Average Speed = Total Distance Covered/Total Time taken

Solution:

Average Speed = 6000/20

Average Speed = 300 m/s

If you want it in km/hr

=> 1080 km/hr

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
