need to solve a word problem using linear equation in slope form.
Ben walks 3 miles per hour, and runs at 6 miles per hour. Runs and walks a total of distance of 210 miles per week.
Is this correct
210 = 3/6m +b  equation to show relation of hours run to walk
B. is Ben runs for 25, how many does he walk
210 = 6(25) +3(x)

nope. distance = speed * time
If the walk/run times are w and r, then
3w + 6r = 210
r = 35  1/2 w
w = 70  2r
you say Ben runs for 25. 25 what? hours, minutes, miles?
If miles, then the run time is 25/6 hrs.
Use that to find the w value
Your equation hints that he ran for 25 hours. I think you will find that it will be hard to come up with a reasonable value for x.
