Question

For each mile Jason runs Megan runes 1/4 mile farther if Jason ran 6 miles how far did Magen run ?

Answer 1

M=1.25*J
M=1.25*6
M=7.5 miles

Answer 2

Let, Jason = J and M = Megan

M = J(1 + 1/4) 

So putting 6 where J is and solving:
M = 6(1 + 1/4)
M= 7.5

When Jason runs 6 miles Megan runs 7.5
