100 kms - 2hours
60 kms - 1 hour
total distance 160 kms
total time = 3 hours
speed = distance / time
160/3
53.33 kms/hour

r*t=d
r=d/t
r=160/3
r=53 1/3 mph

You can put this solution on YOUR website!

average speed = distance traveled divided by elapsed time.
A = d/t
A = 100/2
A = 50
Let T = total average speed for whole trip
T = (50) + (60)/1
