You drive 10 meters backwards and then 20 more meters backwards in 30 seconds. What is your average velocity?

Average velocity= 1 m/s

Explanation:

Step one:

given data

total distance covered =  10 meters backwards+  20 more meters backwards

toatal distance= 10+20= 30 meters

time taken = 20 seconds

Required

The average velocity

Step two:

the expression for the average velocity is

Average velocity= total distance/total time taken

Average velocity= 30/30

Average velocity= 1 m/s
