You get out of school and walk north for 20 minutes. Youtravel 1.6 km. What is your average velocity?1

Sagot :

Velocity is defined as speed in a specified direction. The formula for calculating speed is expressed as

Speed = distance/time

Since the direction is north, time = 20 minutes and distance = 1.6km

We can convert 20 minutes to hour(60 minutes = 1 hour). it becomes 20/60 = 1/3 hour

Speed = 1.6/(1/3) = 4.8 km/hr

The average velocity is 4.8km/hr northwards
