A vehicle travels 200 metres in 5 sec and then another 250 metres in 5 sec. What is its average speed (in meters/sec)?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 45.
Total distance = 200 + 250 = 450 m
Total time = 5 + 5 = 10 sec
Average speed = 450/10 = 45 m/s
