A vehicle travels 60 km at 20 km/h, then 60 km at 30 km/h, with no stops. What is its average speed for the whole trip?
A20 km/h
B24 km/h
C26 km/h
D25 km/h
Answer & Solution
Correct answer: B. 24 km/h
The two legs take three and two hours; total distance 120 km divided by total time five hours gives 24 km/h.
