1 answer:
Answer:
22(c)
Step-by-step explanation:
Our current proportion is
15 miles
-------------
1 hour
We need feet per second.
Lets convert!
15 miles= 79200 feet(used googl to find this)
1 hour=3600 seconds(also used googl to find this)
( i know its not spelled that way brainly wont let me write the whole word out)
Now, our proportion is:
79200 feet
-----------------
3600 seconds
HOWEVER, this can be simplified!!!!
79200/3600=22
Final answer: 22, or C.
