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
