Explanation:
The formula for calculating the percent change in a value between two points in time is:
p
=
N
−
O
O
⋅
100
Where:
p
 is the percent change - what we are solving for in this problem.
N
 is the New Value - 62 inches in this problem.
O
 is the Old Value - 56 inches in this problem.
Substituting and solving for 
p
 gives:
p
=
62
−
56
56
⋅
100
p
=
6
56
⋅
100
p
=
600
56
p
=
10.7
 rounded to the nearest tenth.

Your friend's distance from her starting point to your position is decreasing until she passes by you.  This distance is D(t) = 100 ft - (20 ft / sec)t.  We'll assume that your friend doesn't actually pass by you; she just gets closer and closer, from her initial 100 ft distance from you.  Then:
D(t) = 40 ft = 100 ft - (20 ft / sec)t.  Simplifying, we get:
-60 ft = -(20 ft / sec)t, and thus t = 3 sec.
