The Correct Option is B
Solution and Explanation
To find the average speed, use the formula: \[ \text{Average speed} = \frac{\text{Total distance}}{\text{Total time}}. \] The total distance is 60 km, and the total time is 1 hour and 30 minutes, or 1.5 hours. \[ \text{Average speed} = \frac{60}{1.5} = 40 \, \text{km/h}. \] Thus, the correct answer is (B) 45 km/h.
