Question

Find the average speed of Sanjay, who covers the first 150 km in 4 hours and the next 250 km in another 4 hours.

• A. 74 km/hr
• B. 45 km/hr
• C. 50 km/hr
• D. 100 km/hr

Answer 1

Answer:

C. 50 km/hr

Total distance covered = 150 km + 250 km = 400 km
Total time taken = 4 hours + 4 hours = 8 hours

Average speed formula:

$\text{Average speed} = \frac{\text{Total distance}}{\text{Total time}}$

$= \frac{400}{8} = 50 \text{ km/h}$

Final Answer: 50 km/h
