Marta runs a race against her best friend Markesha. Marta runs at a rate of 7 miles in 1 hour. Markesha runs at a rate of 4 miles in 0.5 hour. Who runs at a faster rate?​

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
