Answer:
24 3/4
Step-by-step explanation:
I've had to assume that you meant "add" or "combine."
10 1/4 + 14 1/2
Recognizing that the LCD is 4, we can rewrite this as
10 1/4 + 14 2/4
and so the sum is 24 3/4.

1 mile = 5,280 feet:
9 miles x 5280 feet per mile = 47,520 total feet per hour
1 hour = 3600 seconds.
Divide total feet by seconds per hour:
47,520 feet / 3600 seconds per hour = 13.2 feet per second.
Multiply feet per second by number of seconds for distance traveled:
13.2 feet per second x 15 seconds = 198 total feet.
