Answer:
David took 32 more steps
Explanation:
first we need to find out how many steps each person takes every one mile to find that out we divide the steps by how many miles .
megan: 9780÷5= 1956 steps in one mile
David: 11928÷6= 1988 steps in one mile
then you subtract to find by how many more steps .
1988-1956 =32
david took 32 more steps
