To find the average speed, use the formula:

Average Speed = Total Distance / Total Time

---

Step 1: Total Distance  

= 30 km + 30 km = 60 km

---

Step 2: Time taken in each segment

- First 30 km at 40 km/h  

  Time = Distance ÷ Speed = 30 ÷ 40 = 0.75 hours

- Next 30 km at 20 km/h  

  Time = 30 ÷ 20 = 1.5 hours

---

Step 3: Total Time  

= 0.75 + 1.5 = 2.25 hours

---

Step 4: Average Speed  

= Total Distance ÷ Total Time = 60 ÷ 2.25 = 26.67 km/h
