Evelyn is waiting in line for concert tickets. she is 2.5 blocks from the ticket booth. 16 blocks equals 1 mile. each person takes up about 2 feet in the line. which calculation can be used to find about how many people are ahead of evelyn in line?

Step 1
Convert blocks to miles
I apply a rule of three
16 blocks equals >  1 mile
2.5 blocks > X
X=2.5/16=0.15625 miles

Step 2
Convert miles to feet
we know that
1 mile> 5280 feet
0.15625 milesX
X=0.15625*5280= 825 ft

Step 3
Convert feet to numbers of persons in line
we know that
1 person> 2 ft
X> 825 ft
X=825/2=412.5> 413 persons

the answer is about 413 persons are ahead of Evelyn in line

25. 22 + 1 2 25
