55 ______/ _____ ´ 1000 _____/1 ______ ´ 1 ______/60 ______
´ 1 _____/60 _____ = 15 _____

Answer 1

55km/1hr x 1000m/1km x 1hr/60min x 1min/60sec =

(55 x 1000)/(60 x 60) =

55000/3600=

Answer: 15.28 m/sec

Answer 2

Answer:

916.7 m/s

Explanation:

Given:

The value of speed = 55 km/hr

To determine:

The corresponding value in meters/second i.e m/s

Formula:

Step 1:

Convert km to m

1 km = 1000 m

Therefore, 55 km = 55 km * 1000 m/1 km = 55,000 m

The speed now is = 55,000 m/hr

Step 2:

Convert hr to sec

60 sec = 1 hr

Speed = 55,000 m/hr *  1 hr/60 sec = 916.7 m/s
