Given:
Distance: 2 kilometers or 2000 meters
Time = 20 minutes
Determine the average speed.
Average speed formula: v = change in distance / change in time
v = d/t
Solution:
Since we do not have any factors that contribute to the change in distance and time, we simply substitute the value of distance and time to the formula for the average speed.
v = 2 km/20 minutes
v = 0.1 km/min
Solve in meters:
v = 2000 m/ 20 mins
v = 100 m/minute
