Distance trevelled = 30 km
Speed =6km/hr
Time = Distance / speed
= 30 /6 = 5hours
Average speed =Total distance/total time
=30+ 40 \5+5 = 70/10 =7km/hr

Step-by-step explanation:
total distance = 30km + 40km = 70km
total time = (30/6) hrs + 5 hrs
= 5+5 = 10hrs
average spee = total distance traveled/total time taken
= 70km/10hrs = 7km/h
