400,246 ( 200,200-77=200,123 divide by .5= 400,246
4(1/2x7)=12 <=> x28/2=12
x=12*2/28=24/28=12/14=6/7
Answer:
The fastest runner is Katie
Step-by-step explanation:
In order to determine this, we must first put them all in the same terms. For the purpose of this, we will put them all in feet per second.

Zach
576 feet/46 seconds = 12.52 ft per second
Tony
1 mile/533 seconds = 5280 feet/533 seconds = 9.91 ft per second
