Correct Answer: 56 miles per hour
Solution : Let's denote the total distance travelled as $D$ and the total time as $T$. T 1 = 2 hours and T 2 = 3 hours Speed 1 = 50 miles per hour and Speed 2 = 60 miles per hour ⇒ Distance covered D 1 = 2 × 50 = 100 miles ⇒ Distance covered D 2 = 3 × 60 = 180 miles ⇒ Total distance = D 1 + D 2 = 100 + 180 = 280 ⇒ Total time = 2 + 3 = 5 hours ⇒ Average speed = $\frac{\text{Total distance}}{\text{Total time}}$ = $\frac{280}{5}$ = 56 Hence, the correct answer is 56 miles per hour.
