If you drive from your house in Denver to Colorado Springs, and drive 60 meters in the first hour, 45 meters in the 2nd hour, and 30 meters in the third hour, what is your average speed?
What is
The distance ΔD traveled is D = 60 meters + 45 meters + 30 meters = 135 meters. The time Δt = 1 hr + 1 hr + 1 hr = 3 hrs x 60min/hr x 60 sec/min = 10800 seconds. Now use the formula for average speed.
s = ΔD/ Δt
s = 135 meters/10800 seconds
s = 0.0125 m/s
?
