Answer: 770 feet
There are 60 minutes in 1 hour and 60 seconds in 1 minute. Therefore, there are 60X60 or 3600 seconds in one hour.
If a motorcycle is traveling at 75 miles per hour, then it travels at 75/3600 or .0208 miles/second. .0208 miles converted to feet is .0208X5280 or 110 feet.
In 7 seconds, the motorcycle travels 7X110 or 770 feet.
