Answer: The average speed is: 23 and 1/3 km per hour
First you drive 30 km in 1 hour. Add 40 km and you get 70 km. This distance is driven in 1+2 hours= 3 hours. 70 km in 3 hours make: 70/3 = 23 and 1/3 km/hr.
Step-by-step explanation:
Total Distance travelled = 30+40 = 70 km
Total Time taken = 1+2 = 3 hours
Average Speed = 70 / 3 = 23.33 km/ hour
