A car is traveling at a constant speed. It travels 3 1/2 miles in 5 1/4 minutes. How many minutes will it take the car to travel 70 miles

The answer is 122 1/2 minutes.

Step-by-step explanation:

I got this answer by first subtracting 5.25-3.50=1.75 and that was how many minutes it took per mile then I multiplied 1.75x70=122.50 to get my answer.

If my answer is wrong im sorry this is my first one on this site.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
