Answer:
distance=rate*time
d=20*(1/2) (30 minutes=1/2 hour)
d=10 km traveled
d=rt
30=r*1 (60 minutes=1 hour)
30=r
r=30 km per hour
total distance=rate*total time
total distance=10 km+30 km=40 km
total time=(1/2) hour+1 hour=1 1/2 hours or 1.5 hours
40=rate*1.5
rate=40/1.5
rate=400/15
rate=80/3 (you don't have to simplify if you don't want to)
rate=26.666... km per hour or 26 2/3 km per hour for the average speed
so make me brainlinest answer ok
