-Take what you know already:
100 yards = 300 feet
1 mile = 5280 feet
Traveling at 60mph means you will travel 1 mile in 1 minute, so given that, you travel 5280 feet in 1 minute.
Divide 5280 by 60 to determine how far you go in 1 second, which is 88 feet per second.
Now divide that by 300 feet (100 yards), and you get 3.41.
At 60 mph, you would travel 100 yards in 3.41 seconds.3.4 seconds
