A car moves through 20m in 3 minutes and the next 50 km at a speed of 100 km/h. What is the approximate average speed of the car?
Correct Answer:
Average Speed =
First 20m in 3 minutes or 180 seconds
and next 50 km at speed of 100 km/h then time = hours = hours = 1800 seconds
Average Speed =
Average Speed = = 25.26 m/s
औसत चाल =
पहले 20 मीटर के लिए 3 मिनट या 180 सेकंड का समय लगता है
तथा अगले 50 km के लिए चाल 100 km/h है तब लगा समय = hours = hours = 1800 seconds
औसत चाल =
औसत चाल = = 25.26 m/s
