Ok first you have to convert 100 miles to feet.
A mile is 5,280 feet
100x5,280
528,000
Thats how much feet per hour. Now we need to find feet per second. So lets divide 528,000 by 60
528,000/60
8,800
Now we know 8,800 is how much feet per minute now we divide it once more by 60 to find feet per second.
8,800/60
146 2/3
So your answer is 146 2/3ft/sec
