Answer:
3.76 m/s.
Explanation:
Velocity in mile per hour (mph) = 8.4 miles per hour
Velocity in metre per second (m/s) =?
Next, we shall convert 8.4 mph to ft/h. This can be obtained as follow :
1 mph = 5280 ft/h
Therefore,
8.4 mph = 8.4 mph / 1 mph × 5280 ft/h
8.4 mph = 44352 ft/h
Next, we shall convert 44352 ft/h to in/h. This is illustrated below:
1 ft/h = 12 in/h
Therefore,
44352 ft/h = 44352 ft/h / 1 ft/h × 12 in/h
44352 ft/h = 532224 in/h
Next, we shall convert 532224 in/h to m/h. This can be obtained as follow:
39.37 in/h = 1 m/h
Therefore,
532224 in/h = 532224 in/h / 39.37 in/h × 1 m/h
532224 in/h = 13518.51664 m/h
Next, we shall convert 13518.51664 m/h to m/min. This is illustrated below:
1 m/h = 1/60 m/min
Therefore,
13518.51664 m/h = 13518.51664 m/h / 1 m/h × 1/60 m/min
13518.51664 m/h = 225.30861 m/min
Finally, we shall convert 225.30861 m/min to m/s. This is illustrated below:
1 m/min = 1/60 m/s
Therefore,
225.30861 m/min = 225.30861 m/min / 1 m/min × 1/60 m/s
225.30861 m/min = 3.76 m/s
Therefore,
8.4 miles per hour is equivalent to 3.76 m/s.
