Question : If a train travels 1000 km from Bangalore to Mumbai and the journey takes 10 hours, then what is the train's average speed in km per hour?
Option 1: 100 km/hr
Option 2: 90 km/hr
Option 3: 120 km/hr
Option 4: 80 km/hr
Correct Answer: 100 km/hr
Solution :
Total distance = 1000 km
Total time = 10 hr
Average speed = $\frac{\text{Total distance}}{\text{Total time}}=\frac{1000}{10}= 100$ km/hr
Hence, the correct answer is 100 km/hr.
