Ответ:
12 miles per hour
Step-by-step explanation:
The math formula says that 1 foot per hour is equal to 1/5280 mile per hour.
Lets convert 15 feet per second to per hour.
15 * 60 * 60 =54,000 feet per hour.
Now let's use the equation to convert the feet per hour into miles per hour.
54,000/5,280 = 10.2 mph
12 miles per hour is faster.
