This is not my answer I found it from another brainly
From the beginning we know we are dealing with two different rates. Distance is equal to (Speed X Time). We have two different speeds though. We will call the min speed = x and the max speed = y. With those two ideas in place we can make two equations for both Tony and Rae.
Tony:
2x+3.5y=355
Rae:
2x+3y=320
Now you can solve the equations by subtracting Rae's equation from Tony's
.5y=35 solve for y and you get 70
Now plug that y value back into either equation and you can solve for x. I'll use Rae's distance:
2x+3(70)=320
x=55
A proper fraction is when the numerator is smaller then the denominator .
so ur answer is 3/4
** fractions are improper if the numerator is bigger then the denominator.
and when the numerator and denominator are the same, the fraction equals 1
Answer:
(Area of circle a)/5
Step-by-step explanation:

A. T. S.A =2* AREA OF TRIANGLE +PREIMETER*5.56
VOLUME=AREA OF *LENGTH[ 5.56]
B. T. S. A=πR{R + SLANT HIGHT }
VOLUME=1/3*π*R*HIGHT{ 7 }
volume of a sphere is 3 by 4 by R cube and surface area of a sphere is 4 Pi R Square
