Given:
Distance = 60 km east and 80 km north
Time = 2 hours
Determine the average speed.
Formula for average speed/average velocity:
vave = Total Distance/ Time
Solution:
Substitute the given values of distance and time to the formula.
vave= 60 km + 80 km / 2hours
vave = 140 km/2 hours
vave = 70 km/hr
Final answer:
vave = 70 km/hr
