distance travelled by a train is 495 km in 4 hours 30 minutes, what is its speed in m/s? July 22, 2021 by Đan Thu distance travelled by a train is 495 km in 4 hours 30 minutes, what is its speed in m/s?
Answer: 9.09m/s Explanation: Speed = Distance/Time Distance = 495km Time = 4 hr 30 min = 4 hr 1/2hr = 4.5 hr Therefore, Speed = 495/4.5 = 110km/h Now to convert km/h to m/s 110 x 1000/ 110 x 110 110 cancels out each other, we are now left with 1000/110 = 9.09m/s Reply
Answer:
9.09m/s
Explanation:
Speed = Distance/Time
Distance = 495km
Time = 4 hr 30 min = 4 hr 1/2hr = 4.5 hr
Therefore, Speed = 495/4.5 = 110km/h
Now to convert km/h to m/s
110 x 1000/ 110 x 110
110 cancels out each other, we are now left with
1000/110 = 9.09m/s
