A man travels 60 km in 2 hours and then travels 40 km in 1 hour. Find his average speed for the entire trip.
Correct: A
The total distance traveled is 60 + 40 = 100 km, and the total time taken is 2 + 1 = 3 hours. The average speed is given by the formula AS = Total Distance / Total Time, where AS is the average speed. Substituting the values, we get AS = 100 / 3 ≈ 33.33 km/h. However, the closest option to this is 30 km/h.
