top left: speed = 2.7 miles per hour  = 2.7 MPH

top right: speed = 0 miles per hour  = 0 MPH

bottom left: speed = 4 miles per hour  = 4 mi/h

bottom right: speed = 2 miles per hour  = 2 mi/h

and so, the fastest is bottom left. And pay attention in class! i'm in highschool and Iearned this in 6th grade!

Step-by-step explanation:

key: speed= distance/time

distance= speedxtime

time=distance/speed

top left: 8/3= 2.66667 MPH= 2.7 MPH

top right: 0/8= 0 MPH= 0 MPH

bottom left: 8/2= 4 MPH= 4 MPH

Use the formula A=P(1+r)" to solve the following problem.
LenKa [72]

Answer:

r= 0.19

Step-by-step explanation:

A= $708,050

P=$500,000

'' = 2

$708,050= $500,000(1+r)^2

-Divide $500,000 by both sides

1.4161= (1+r)^2

-Square Root on both sides

1.19= 1+r

-Subtract 1 on both sides

r= 0.19
