Danielle can run one mile in 8.835 minutes alex can run 1 mile and 9.75 minutes how much longer in minutes does it take for alex to run 1 mile that it takes danielle

0.915 minutes

Step-by-step explanation:

First, take the 9.75 minutes that it takes Alex and the 8.835 minutes it takes Danielle.

Second, line up the numbers annexing zeros as placeholders as needed.

Third, subtract them

9.750

-8.835

0.915

rounding to the nearest thousandth would be 452,000

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
