Answer:22.37 mph
Explanation:
100 meters = 0.062137 miles
Assume constant speed over the distance.
0.062137 miles in 10 sec
0.372822 miles in 60 sec = 1 minute
22.36932 miles in 60 minutes
22.37 mph rounded to 2 decimals
They each have one valence electron in their outer shell, but they are also on the same row (period). If you follow this pattern, potassium will also have one valence electron.
Hope this helps!! :)
