Answer:
Ron runs the fastest.
Step-by-step explanation:
To see who's the fastest you should convert everyone's speed into one unit (feet per second for this example).
Liz
13 feet per second (doesn't have to be converted).
Ron
He runs 495 feet in 34 seconds, so he runs 495 feet ÷ 34 ≅ 14.55882 feet per second.
Katie
1 mile = 5280 feet. She runs 5280 feet in 506 seconds, so she runs 5280 ÷ 506 ≅ 10.43478 feet per second.
Will
1 minute = 60 seconds. He runs 666 feet in 60 seconds, so he runs 666 ÷ 60 = 11.1 feet per second.
Results
Liz - 13 feet per second
Ron - 14.55882 feet per second
Katie - 10.43478 feet per second
Will - 11.1 feet per second
As the results show, Ron runs the fastest, Liz the second fastest, Will the third fastest and Katie the fourth fastest.

Answer:
Yes, Mark has $16 left and only has to pay his sister $15.
Step-by-step explanation:
1/5=x/20
use cross multiplication to find (x),which represents 20% of 20.
x/20=1/5 (cross multiply)
20=5x (divide by 5 on both sides)
x=4
This tells you that Mark gave $4 to the local charity.
20-4=16
Subtracting 4 from his original amount, he now has $16 left.
