Question

Find Marcus' walking speed?

Answer 1

did you fill out the table

Answer 2

lets start with that

Answer 3

distance = rate * time

rearranging

time = distance / rate

Answer 4

this gives us two equations
t = 1/r
t = 2.5 / ( 6 + r )

since time is the same in both equations (that is given in the directions), we have

1/r = 2.5 / ( 6 + r )

Answer 5

now you can solve for r , by cross multiplying

Answer 6

@perl does r = 6?

Answer 7

@perl please
